PyPI Workflow

[lukelowry]

Using GitHub actions to publish ESA releases to PyPI could improve the maintainability of this repository. It is not difficult to set up, but someone with the proper authority would need to configure it on PyPI.

Tutorial and documentation:

• The Github Action pypi-publish
• The Python guide for trusted publishing

I don't think it's possible to run the functionality tests via GitHub actions (due to PowerWorld installation requirements). Still, we could use a workflow to test the Python version compatibility of the module.

This is just a suggestion. This would simplify the release procedure.
