Add WLED support (#1092)

A component to support [WLED](https://github.com/Aircoookie/WLED/wiki/UDP-Realtime-Control).
This allows to control addressable LEDs over WiFi/UDP, by pushing data right into LEDs.

The most useful to use [Prismatik](https://github.com/psieg/Lightpack) to create
an immersive effect on PC.

It supports all WLED protocols:
- WARLS
- DRGB
- DRGBW
- DNRGB
- WLED Notifier
