[Feat]: Implement menu handling

[anarion80]

The request

Implement menu handling from Tech API. This would enable control for a lot more devices like boilers, pumps, valves, etc.

This will require access to a device using menu API in emodul.eu and some reverse engineering, as the menu API is not very well documented.

This is not likely to be implemented anytime soon. Any help is wanted and appreciated.

I will try to take a look into that. Firstly I will focus on implementing that in API.
