Replace black and flake8 with ruff

[cclauss]

Fixes #70

• Switch to ruff #70

After this ruff lint PR is merged we can have a followup PR to enable ruff format in pre-commit. We should first decide if we want to keep line-length at 99 or the default of 88.

I'm fine going to 88, but lots of comments need to be adjusted:

partitionmanager/cli.py:410:89: E501 Line too long (96 > 88)
partitionmanager/cli_test.py:228:89: E501 Line too long (94 > 88)
partitionmanager/cli_test.py:231:89: E501 Line too long (94 > 88)

I like ruff though, this is great.

We can move to 88 and resolve the line lengths at the same time as we add --check to the ruff format; I'll open a follow-on.
