refactor: switch to Poetry for env+dep management (#127)

I've been using Poetry because it takes the hassle out of virtualenv management and has sane defaults that just work for building artifacts and uploading to PyPI.

Because I had to redo how tests were run, I went ahead and removed the Tox testing requirement too and so I had to redo the Github Actions for testing too.

One thing I didn't anticipate is that Github Actions caching doesn't work for Poetry, only with `requirements.txt` and Pipenv https://github.blog/changelog/2021-11-23-github-actions-setup-python-now-supports-dependency-caching/

## Verifying the change
I compared `python setup.py build` vs `poetry build` and the only difference was some top level meta differences and Poetry added the `tests` directory which is fine. Both have the `.html` templates which is the important thing.
