move setup.cfg to pyproject.toml

[bjlittle]

🚀 Pull Request

Description

This PR migrates the setup.cfg to the pyproject.toml.

For the motivation, see pep621.

Note that,

• the flake8 configuration now lives in the dedicated .flake8 file. When we migrate to tox, then the .flake8 can then be migrated to the tox.ini - see here. Additionally, the flake8 configuration may be further consolidated if we choose to adopt ruff 😉
• the PyPI dependencies have not been indirectly migrated into the pyproject.toml. Rather, they are now explicitly defined under the requirements directory in *.txt files. Most devs have fallen foul of updating conda dependencies and forgotten about pypi dependencies, as they were obfuscated within the setup.cfg. Hopefully, banking all our dependencies within the same directory will alleviate this issue
• this pr is related to automate pypi manifest checking #5259 i.e., the MANIFEST.in requires to be updated to include the requirements/*.txt PyPI dependency files
• by doing this work, I since discovered mo_pack is not available on PyPI, so it has been removed
• the optional dependency groups are now dev, docs and test, instead of docs, test and all (which included dev, docs and test via using convenience syntax within the setup.cfg)

• Switch to tox #5184

by doing this work, I since discovered mo_pack is not available on PyPI, so it has been removed

Possibly a bit worrying, as it is so essential for UM files support.
We need this to be available in the internal SSS environments, so at least requires adjustment of those definitions.

It is available - via Conda

(It's also essential to benchmark file generation)

Thanks to @trexfeathers, #5259 has landed, so I'll rebase and refactor the MANIFEST.in 👍

[bjlittle]

I'll also check to see if any changes I've made here make any of the dev docs stale wrt updating PyPI deps (which now live under the requirements directory) ...

Thanks to @trexfeathers, #5259 has landed, so I'll rebase and refactor the MANIFEST.in +1

Done, see a1bf9e4 and 96b89e1

Done i.e., nothing to do in the docs (that I can see)

My point was, if we now have "one true list" of dependencies (for which 👍 🥇!) , will this also remove it from the conda deps ?

Yeah, from what I can see the ecosystem isn't quite there yet... well, not that I know of, but I'm certainly not an authority on this stuff.

I may ask around at scipy 2023 and see what the word is 👍

[trexfeathers]

OK this is ready to go, but needs a conflict resolved first.

On it now...

@trexfeathers Hmmmm if only we had auto-merge enabled 😉

@trexfeathers Awesome, cheers 🍻
