pynvim needs to be updated to use pyproject.toml

[crowellel]

When I just recently installed pynvim, I was presented with a deprecation warning that stated that starting in pip ver 23.1, pip will require compliance with using a pyproject.toml file for module installation, instead of the legacy setup.py file that pynvim currently uses. Therefore I would recommend updating the package and migrating to a pyproject.toml file for setup as soon as possible to avoid having installation broken when pip starts forcing compliance.

any chance you could send a PR?

I was actually considering doing just that. I've just never worked with packaging before so I figured this would be a good learning opportunity. I'll send the PR once I get it done. I estimate two weeks due to current time constraints.

just saw the same msg today

DEPRECATION: pynvim is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

@badboy1cdx thank you in advance!
