Replace setup.cfg with pyproject.toml

[hoh]

pyproject.toml is the new standard format for specifying package metadata in Python.

The aleph-vm project switched to it recently, see aleph-vm/pyproject.toml.

Documentation is available on:

https://packaging.python.org/en/latest/tutorials/packaging-projects/
https://pip.pypa.io/en/stable/reference/build-system/pyproject-toml/

On aleph-vm, we found the use of the hatch command from the first documentation very handy to run tests and reformat the code.

Hey @ofek, thank you for reaching out! Right now, no one's actively working on it.

We highly encourage people to contribute to the project with PRs, I'd love to review it!

We successfully converted to Hatch in #111 👍

Nice job!
