Typecheck DPT and RemoteValue

[farmio]

Description

So I have tried to type annotate DPT and fell into a mypy rabbit hole. Sorry for this PR from Hell.

For type checking to work these changes were made:

• RemoteValue is Generic now accepting DPTArray or DPTBinary
• split RemoteValueClimateMode into RemoteValueControllerMode and RemoteValueOperationMode
• return the payload (or None) in RemoteValue.payload_valid(payload) instead of True/False
• Light colors are represented as Tuple[Tuple[int,int,int], int] instead of Tuple[List[int], int] now
• DPT 3 payloads/values are not invertable anymore. This was done in the DPT classes, but should be done in RemoteValue.
