move metadata to pyproject.toml

We still need a stup setup.cfg
[until](pypa/setuptools#2816)
setuptools gets proper editable installs
and either
flake8 [**finally**](python/mypy#5205)
gets the hint and support pyproject or
[flakeheaven](https://github.com/flakeheaven/flakeheaven) is usable with
vscode.
