BlueARP updated to v2.2.7

Changes in v2.2.7

1. Added setting for PBend/MWheel/ATouch/OtherCC pass thru
2. BugFix: bluearp didn’t report param change back to host, so automating in FL
via ‘Last changed parameter’ didn’t work
3. Checked and improved patch compatibility back to v2.15
Fixed some bugs in conversion 2.2.5 -> 2.2.6 (it was wrong with midi in ch, midi out ch, curChain)
