[Feature Update]: Add RGB for Yeelight Integration

[RonSijm]

Idea: when chess engine proposes a move - lets say Queen to E5 - every pawn piece can have their own color code. Blinking the code for E5 in blue when the queen should be moved, blinking in red when a pawn should be moved etc etc.

(This feature depends on #30 to be completed first. - because in that isue a FEN to piece position decoder is build, so I can easily use the start position to see which piece is in the start position to determine what color.)

Not sure if piece determination can de used in buttplug.io devices. Could possibly use a different vibration strength or something. If anyone have any bright ideas, feel free to leave suggestions
