Some dirty integration of WS2812FX (based on Adafruit Neopixel) for the SK6812 RGBW leds.

USE:

• Install Adafruit Neopixel (from the lib manager)
• Install ArduinoJSON (from the lib manager)
• Install ArduinoOTA (from the lib manager)
• Install PubSubClient (from the lib manager)
• Install WS2812FX (from a zip download on github)
• Create a config.h file from the example with your own information
• Integrate configuration.yaml into your Home Assistant config

NOTE: If you're using WS2812 LED strip, you should probably set white_value to false on HA configuration. Hopefully the Arduino code should work.

TODO:

• Use setSegment() and multiple colors
• Get rid of the String with some char
• Add HA switch to reset colors to 0 so we can have white only (not possible using the default color wheel on HA)
• Sometimes the code crashed and restarts the ESP. It's possible it's a bug when it cycles to the white led (for instance when using a random color effect), and that it's a WS2812FX bug. But it's not sure it actually reboots because sendState() is not called.
