Added full decompilation of keylab_mk3

[MrMatch246]

All files decompiled using PyLingual; some i had to manually fix and patch but now their pyc files are identical to the original pyc files by Ableton, Apart from this

    try:
        from ableton.v3.control_surface.capabilities import AUTO_LOAD_KEY
    except ImportError:
        from ableton.v2.control_surface.capabilities import AUTO_LOAD_KEY

I dont have the device yet so i cant check if this is needed and i dont know if

from ableton.v3.live import simple_track_name

exists or works in the current version but here you go anyway
