Add Midi behaviour for Stomp mode

It would be good to expand the existing midi options to have all 8 assignable stomp boxes A-G available to toggle (message 0 and 127) via individual CCs like scenes are.

currently we can pick a scene, including those not available on the footswitches if you run the 4+4 scene/stomp configuration, but not the same for stomps. justice for stomps!

Hi there, this request already exists.
