this should all be tested now:
1. invoking against precompiled _pb2.py files provided by user
2. invoking against .proto files provided by user which must be compiled
3. invoking with a special option to use shipped (by us) .proto files
which must be compiled
4. erroring because none of the above occurred
this took some reorganization, but this should finally give me stability
in using this in GP2040-CE's build process
