Move all configuration into pyproject.toml, add x86 mac to CI

[pavelzw]

This PR introduces more modern linters and formatters and merges all config into pyproject.toml

All .py file changes are formatting related to use the more popular black formatting style implemented by ruff, the rest is actual changes.

This PR moves all tooling configuration into one centralized pyproject.toml

Hi @pavelzw, not a maintainer of the project but can you please separate your commits such that the first commit includes all structural changes (including ruff, updating scripts and CI, etc) and the second commit performs the actual formatting? This makes it easier to review and audit/reproduce the code ;)

[pavelzw]

Happy to re-do this once #78 went through as just reformatting is probably a lot easier than actually fixing merge conflicts.

@Garmelon this is ready for review

[Garmelon]

I don't want to switch to ruff right now (maybe in the future though), but the remaining changes look good. I also like the merging of tooling config into pyproject.toml.

Could you please remove ruff and the resulting reformatting?

[pavelzw]

Should I keep the ruff linter instead of isort and flake8 and only revert the ruff format part or remove ruff altogether? I'm not sure flake8 supports configuration inside pyproject.toml and ruff should support a similar featureset like both tools.

I want to keep using the old tools for now. They're written in python, which makes them easier to use in my weird nixos setup (no issues with any compiled binaries).
