Fails if Python package has no requirements: TypeError: 'NoneType' object is not iterable about codemetapy

I released v2.0.1 with the fix, closing this issue, the support for pyproject.toml is tracked separately in #17 now.

Thanks for the feedback! I have implemented your solution now so at least the system won't stumble over having no dependencies.

I agree that things should be made to work with only a pyproject.toml instead of a setup.py, especially as that's the recommended way for the future. I'm currently investigating if I can get importlib.metadata to get to that info, without necessarily installing the entire package and all dependencies. I'd rather not reinvent the wheel and parse the toml manually.
