Modernizing packaging to Poetry, and automate publishing to PyPI

[vtnate]

• Update packaging from setup.py to pyproject.toml managed by poetry
• Add workflow that automatically publishes to PyPI when a release is made on Github
• Bump pre-commit hook versions
• Add ruff_cache to gitignore, so that once ruff is activated we don't keep these cache files on Github

@nllong can we make this change now? I think SEED is still on 3.9...

[vtnate]

Shouldn't be too hard to stick with 3.9. The original didn't have any versioning on dependencies, so I just set the current version of everything. I could enforce older versions of dependencies and that way support 3.9 again, though we might give up 3.13 in the process.

stick with 3.9...

[vtnate]

Not sure why this is still looking for a 3.12 CI run. Maybe because develop is still testing 3.12? @nllong @kflemin please review at your convenience.

once you make sure that Python 3.9 is supported, then merge!
