fix python packaging

[nemith]

The python packaging seems to be broken as reported in #7 where the actual python module is missing from the distribution when isntalling from PyPI or directly from source.

This updates the [tools.setuptools] to use package instead of py-modules.

Note: Also concider using hatchling or flit (both are supported by the Python Foundation) as alternatives to setuptools which is concidered a bit legacy at this point. I'd be happy to change to either one, both are light weight and support full PEP support.

$ python3 -m build
