-NeoPixel library helper functions for Esp8266.
-
-FIXED VERSION FROM https://github.com/Makuna/NeoPixelBus/pull/894
-This library will overlay/shadow the base version from NeoPixelBus 
-
-Written by Michael C. Miller.
-Thanks to g3gg0.de for porting the initial DMA support which lead to this.
-Thanks to github/cnlohr for the original work on DMA support, which opend
-all our minds to a better way (located at https://github.com/cnlohr/esp8266ws2812i2s).
-
-I invest time and resources providing this open source code,
-please support me by donating (see https://github.com/Makuna/NeoPixelBus)
