X-Touch Mini midi controller for darktable

@phrrk

it certainly looks like there is code there that is designed to set all the LED lights to the correct (on or off) state each time there is a midi event

That is encouraging.

I also note that it is possible to send a MIDI message to the X-touch to change the active layer, so something to experiment with together with the lua scripting.
