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

note that the google protobuf project does not recommend shipping
generated _pb2.py files, so that functionality has been removed from the
project. this also partially undoes the previous commit since using the
provided .proto files is less of an issue and also the default now, so
maybe don't spam the console as much

prior MIT-licensed versions can be obtained from the Git history; this
does not revoke those versions
