[#310] Run Ruff check and format on codebase

[alanking]

Addresses #310

Test suite passed.

Please have a look at the config file and see whether there are any tweaks we want to make. The one shown is the default, but we can modify it and point the workflows at it.

Some thoughts:

I didn't do very much work to apply these fixes. Ruff did most of it itself. The GitHub Actions workflow uses --diff, so it will not modify anything in PRs. I might update the README to include a tidbit about running Ruff locally because that was incredibly easy as well. I just ran the docker container as described here: https://docs.astral.sh/ruff/installation

Here's what running the check (linter) looks like:

docker run -v .:/io --rm ghcr.io/astral-sh/ruff check --fix

I included --unsafe-fixes as well to try to fix everything and then combed through the changes and fixed what didn't quite work out the way it should have. You can of course just use --diff to only display a diff like in GitHub Actions.

And here's what running the formatter looks like:

docker run -v .:/io --rm ghcr.io/astral-sh/ruff format

I consider this a forerunner to using Ruff in the python-irodsclient (https://github.com/irods/python-irodsclient) repo. We can try it out here to see if we like it, and, if so, we can apply it there as well.

You can see the GitHub Actions workflow results over in a test PR I made in my fork: alanking#1 Not sure why they won't run here - guess it's different because it's not my repo.

EDIT: And here's what it looks like if the problems aren't gone: alanking#2

Converting to draft until irods/python-irodsclient#726 is a bit further along. We will want to do something similar if not identical in this repo.
