- `sin16_t() / cos16_t()` are faster and more accurate than fastled versions
- `sin_approx() / cos_approx()` are float wrappers for `sin16_t() / cos16_t()` and are accurate enough to replace `sinf()/cosf()`
- `atan2()` is used only in octopus to calculate center offset, new approximated version saves flash
- `tan(), atan(), asin(), acos(), floor(), fmod()` are used only for sunrise/sunset calculation, using wled_math version saves flash
- `beatsinx()` replacements are to make use of new `sin16_t()/sin8_t()` functions to reduce flash size
- Extensively tested surnise/sunset calculation: deviation is 1min. max
- Tested some of the relevant FX and found no visual difference: Julia, 2D Drift, Drift Rose, Ghost rider, Rotozoomer, Palette, Arc 1D expansion
- total flash savings: 7.4k
Retrieving the config in `readFromConfig()` results in defaults being set to both `hourMarksEnabled` (`false`) and `hourMarkColor` (`#0000FF`) due to differences in capitalization compared to how they're saved in `addToConfig()`
* Implement optional hour marks
Time offset did not work
* removed undefined error int in hexstringtocolor
* revert cosmetic changes
* minor cosmetic changes
