Package with hatch

[eevelweezel]

What do these changes do?

This updates pyproject.toml to support new-style packaging with hatch, instead of setuptools / setup.py.

The existing requirements files have been combined into "dependencies" (always installed), "dev" (anything dev, lint, or testing), and "doc" (needed to build the docs). With the optional dependencies, I was trying to follow convention I've seen elsewhere. Feedback would be welcome.

Are there changes in behavior for the user?

Instead of using pip install -r requirements/..., the package can now be installed with pip install -e .[dev,doc] (where "dev" and "doc" are optional dependency groups).

Pre-commit only supports Python 3.9+ as of v3.6.0, so I changed the requirement to pre-commit>=3.5.0 in order to support Python 3.8.

Could we also adopt setuptools_scm to automate the version mangling based on the latest git tags?

Since we're using hatchling, I used hatch-vcs, which delivers the same functionality. I've also rebased against master.
