Clean-up and simplification of strip.service() after individual effect FRAMETIME was removed.
* Activation "_frametime" is now the same for all effects, so effects scheduling based on individual frametime is not needed any more
* Special handling for mode_static is obsolete, because the solid effect does not have a different timing any more
* Ensures a safe fallback segment after servicing to avoid stale state.
* Brightness changes use a capped refresh threshold to avoid excessive redraws.
* remove "return FRAMETIME" from all FX, fix timing for some FX
- all FX now render every frame, no more "speed up" during transitions
* fix missing return by adding FS_FALLBACK_STATIC macro
* add FX_FALLBACK_STATIC also to user_fx
* remove obsolete seg.next_time
* Safety Checks for UI, fix for cfg exceeding LED limit
* improvements to low heap check
* add `isPlaceholder()` to bus, some fixes
* remove `disableForceReconnect` for better future implementation
* add "glitch gating" for C3 and check heapy every 5 seconds instead of every secondd
* replace magic number with the correct define, more robust bus defer by look-ahead
In the event that a Bus fails to initialize, or the memory validation
fails, keep the configuration around so the settings contents don't
change out from under the user.

forgot to adjust the debug condition in my previous commit.
NB: the condition only shows a debug message when the max wait time was exceeded, which can only happen when line 1692 has waited for the maximum allowed time. ->Is this intended?
the timing logic did not work in case that millis()+100 + frametime rolls over; in this case millis() > maxWait, and waiting would be skipped which might lead to crashes.
-> logic slightly adjusted to be robust against rollover.
- if a segment is destroyed or turned inactive, disable the gif player: only one gif player instance can run at a time, if a inactive or destroyed segment uses it, the effect is broken for other segments.
- copy FX ironically copied the source segment on each call, should use reference not a copy!
- speed optimization in color_add, PS fast_color_add and blur functions
- applying more bit and shift manipulation tricks to squeeze out just a bit more speed on color manipulation functions.
- Optimization on blur is based on work by @blazoncek
- Renamed PS fast_color_add() to fast_color_scaleAdd()
- allow more than 10 custom palettes
- move palettes into CPP file
- Fix for minimizing cpal.htm (saves 2k of flash)
- shortened names in cpal, saves about 400 bytes of Flash after packing
- removed async from common.js loading to prevent errors on page loads if the file is not cached
- restricted nubmer of user palettes on ESP8266 to 10
- unrestricted number of user palettes on all other platforms (total max palettes: 256)
- added a warning when adding more than 10 palettes to let the user decide to risk it
- Bugfixes in palette enumeration, fixed AR palette adding
- AR palettes are now also added if there are more than 10 custom palettes

* Improved heap and PSRAM handling
- Segment `allocateData()` uses more elaborate DRAM checking to reduce fragmentation and allow for larger setups to run on low heap
- Segment data allocation fails if minimum contiguous block size runs low to keep the UI working
- Increased `MAX_SEGMENT_DATA` to account for better segment data handling
- Memory allocation functions try to keep enough DRAM for segment data
- Added constant `PSRAM_THRESHOLD` to improve PSARM usage
- Increase MIN_HEAP_SIZE to reduce risk of breaking UI due to low memory for JSON response
- ESP32 makes use of IRAM (no 8bit access) for pixeluffers, freeing up to 50kB of RAM
- Fix to properly get available heap on all platforms: added function `getFreeHeapSize()`
- Bugfix for effects that divide by SEGLEN: don't run FX in service() if segment is not active
-Syntax fix in AR: calloc() uses (numelements, size) as arguments
* Added new functions for allocation and heap checking
- added `allocate_buffer()` function that can be used to allocate large buffers: takes parameters to set preferred ram location, including 32bit accessible RAM on ESP32. Returns null if heap runs low or switches to PSRAM
- getFreeHeapSize() and getContiguousFreeHeap() helper functions for all platforms to correctly report free useable heap
- updated some constants
- updated segment data allocation to free the data if it is large
- replaced "psramsafe" variable with it's #ifdef: BOARD_HAS_PSRAM and made accomodating changes
- added some compile-time checks to handle invalid env. definitions
- updated all allocation functions and some of the logic behind them
- added use of fast RTC-Memory where available
- increased MIN_HEAP_SIZE for all systems (improved stability in tests)
- updated memory calculation in web-UI to account for required segment buffer
- added UI alerts if buffer allocation fails
- made getUsedSegmentData() non-private (used in buffer alloc function)
- changed MAX_SEGMENT_DATA
- added more detailed memory log to DEBUG output
- added debug output to buffer alloc function
* updated color scaling to preserve hue at low brightness resulting in much better colors
* replace NPBlg with NPB, moved brightness scaling to bus manager
* improved gamma table calculation: fixed mismatch in inverting gamma table calculation: inversion should now be as good as it gets
* code cleanup, fixed gamma being applied in unnecessary places
Improvements to ABL handling:
- removed strip level handling, ist now all done on bus level
- limiter now respects pixel mapping
- proper handling of white channel
- improved current estimation
- current is now always correctly reported to UI
- minimal FPS impact if the ABL is not limiting but slighly higher impact for global ABL limit due to double-scaling
- moved brightness scaling to BusDigital
- created new header file colors.h to be able to access color functions in bus-manager.
- updated colo_fade() with better video scaling to preserve hue's at low brightness
- added IRAM_ATTR to color_fade (negligible speed impact when compared to inline and benefits other functions)
- added IRAM_ATTR to color_blend as it is used a lot throughout the code, did not test speed impact but adding it to color_fade made it almost on-par with an inlined function
Additional changes:
- fixes for properly handling `scaledBri()` (by @blazoncek)
- also use bit-shift instead of division in blending for ESP8266
- improvements for faster "softlight" calculation in blending
- changed some variables to uint8_t to maybe let the compiler optimize better, uint8_t can be faster if read, store and set are all done in uint8_t, which is the case in the ones I changed
- various minor code formatting changes
this fixes a very long loop when an overflow was happening in palette blending.
- reset prevPaletteBlends to prevent overflow
- add safety check in case overflow should still happen in another combination (or in future changes)
* Make color_wheel rotate in HSV sapce instead of linearly interpolating R->G->B
* Remove the rainbow wheel option, as that is the same as the rainbow palette
* Use hsv2rgb for color_wheel
