Bundle a poetry.lock file with the release

This will enable easier deployment for STSci.

If possible, bubble the implementation up to the LINCC PPT.

From in-person chat, a reasonable approach may be:

inside /.github/workflows/publish-to-pypi.yml

pip install .
<create poetry.lock>
pip install .[dev]
pytest
<publish to pypi with the poetry.lock file>

This bundles the lock file, and runs the unit tests at publish time (which is a current oversight).
