[IDEA] Enhanced rotary encoder & button input

[Tim Curtis]

Hi Peter,

Great work :-) I'll see what it might take to integrate these and provide UI config panels for them. One challenge is that the maintainer of WiringPi deprecated the project before fixing some bugs that prevent it from working correctly on Pi-4B :-(

I had to switch to the Python based RPi.GPIO library because of this.
