Subject: [PATCH] Fix bug when using --module foo and foo is a directory.

* The current check would try to load that as a file and fail.
* Pointing to the file itself (foo/__init__.py) doesn't work because then the _is_submodule check fails, because the module name is a random UUID in that case.
* `PYTHONPATH=. pydantic2ts.py --module foo --output foo.ts` works in this case.
