Issue converting ableton project to midi

[perivar]

Hi,
Thanks for a very interesting tool.

I tried to convert an ableton project (als) file to midi and it failed in "functions_compat\trackfx_to_numdata.py" in the groups_inside loop.

The only fix I could think of was to enclose the code in a try except, which fixed my problem.
The issue is that the groups_inside object does include a id that the idnum_group does not.

try:
    for groupidnum in groups_inside:
        output_ids[groupidnum][3] = [idnum_group[groups_inside[groupidnum]], 1, None]
except Exception as error:
    # handle the exception
    print('[error] An exception occurred:', error) 

Cheers
