Feature Request - Support for adressable leds (WS21812, etc)

[qawsed55]

Hello! Sorry for pore English. It would be nice if make ability to drive addressable leds. For example we can make board with leds and device names near leds. Leds will show by color or flashing if something wrong. On web page we can set system how to show each event (ok, troubles, disconnect, offline, system errors, etc) To drive this leds we need just one pin of raspberry and a little power ))
