More Poetry support, move some metadata to pyproject.toml

[kafonek]

Good morning maintainers. This PR for your consideration moves some metadata from Cargo.toml to pyproject.toml, and adds maturin / pytest as Python dev dependencies in pyproject.toml so that virtualenv management can be handled with poetry.

• poetry install && poetry run maturin develop && poetry run pytest for local development
• I think license will show up in https://pypi.org/project/y-py/ after this (currently does not)

Thanks @kafonek, but I would prefer if we moved to hatch.

Thanks @davidbrochart, I'm most familiar with using Poetry in our work repos. I remember looking briefly at Hatch a few months ago after the 1.0 announcement and not seeing anything that really motivated me to try it out. It seemed like one of the selling points was "tox-esque" matrix of versions support, which we didn't need.

I am annoyed at Poetry for having potentially breaking changes between 1.1x and 1.2x around the dependencies block.

There's two small pain points I hit while trying to make an equivalent hatch branch to this one. First, I don't see a way to configure hatch to create virtualenv's at the current working directory. I like that my VSCode defaults to activating ./.venv/bin/python and using that as the interpreter for linting. Second, I like poetry add to update pyproject.toml for me rather than looking up versions at pypi.org or elsewhere. Is there a hatch add I'm missing? Maybe I'm missing the right hatch tutorial.

Maybe look at this plugin?

I don't think so, but it doesn't seem so important to me, as you probably want to pin lower and upper bounds, which depends on things that the tool cannot guess anyway.

And I'm here still using conda directly 😂
