add `pyproject.toml`, etc.

We should probably add in pyproject.toml, and with that we can streamline:

• setup.py, setup.cfg
• move requirements into pyproject.toml and remove individual reqs files

Moreover, if we want to adopt setuptools_scm for version control ruff for linting we can:

• get rid of setup.py, setup.cfg, versioneer.py, _version.py, .pylintrc, .coveragerc

Note that unlike versioneer, setuptools_scm only loads the version during the installation, so when having an editable install (pip install -e .), the version it shows is static and doesn't show the actual commit situation from the last tag once you change something.

Although this is a relative drawback from using versioneer, my interpretation is that the pros of using setuptools_scm far outweigh the cons. Things just seem to "work". What are your thoughts, @martinfleis ?

[martinfleis]

Yeah, I agree. This is mostly a dev-focused little thing but I prefer a clean repo over up-to-date commit hash in the version.
