The babelizer should be pip-installable

[mcflugen]

The babelizer is available on conda-forge but I don't there is any reason it shouldn't also be available on PyPI. To make this happen, we could add a workflow that uploads a source distribution to PyPI when new versions are released.

This is also #80.

@mdpiper Can you add me as an owner of the babelizer project on TestPyPI?

[mdpiper]

@mcflugen Too funny. You're now the owner.
