Digital RGB LED (WS2812/SK6812/NeoPixel/WS2813/etc.) drivers for the ESP32
Based upon the ESP32 WS2812 driver work by Chris Osborn
### Things that work currently
This currently works well with WS2812/NeoPixel LEDs - I expect SK6812 to work equally well.
This should work fine with WS2813 (no hardware to test this)
There are working demos for Espressif's IoT Development Framework (esp-idf) and Espressif's Arduino-ESP32 core
### TODO
- APA102/DotStar support
- Better API
- More demos
