MSuperLooper: momentary widgets to show state of loops

I was only meaning to route each track. For the loops, you will need a way to show this in the widgets. From what I can see, the loop parameter is a single parameter, so you will either need to accept this as a horizontal fader (instead of buttons) or create a script to make the pads highlight the selected loop.

This is similar to what was done in this Helix Native template to use buttons to select the snapshot.
