When running animations, part of the ledstrip doesn't follow the pattern and acts weird sometimes. Investigate the problem and fix it

Seems like NeoPixel library doesn't support RMT on the ESP32 which causes the pixel data to not be timed correctly and show glitches: https://github.com/adafruit/Adafruit_NeoPixel/issues/139 NeoPixelBus does support RMT: https://github.com/Makuna/NeoPixelBus/issues/152#issuecomment-500283195 Don't know about FastLED

A temporary solution is to add a very small delay of 1-2ms before showing the strip to make sure all data is present.
