Introduce pre-commit hooks and a package manager

[bojobo]

Per pre-commit:

Git hook scripts are useful for identifying simple issues before submission to code review. We run our hooks on every commit to automatically point out issues in code such as missing semicolons, trailing whitespace, and debug statements. By pointing these issues out before code review, this allows a code reviewer to focus on the architecture of a change while not wasting time with trivial style nitpicks.

For further development and contributions by others it makes sense to introduce the use of pre-commit hooks. They keep the code formatted and make sure that any contributor does not commit to main directly but rather to a different branch, which then can be merged if proven useful.

Similarly a package manager simplifies the setup for development, so that new contributors do not have to create a virtual environment by themselves but rather can simply execute the init command. I propose using uv. I find it easier to use than the competition and the speed is unmatched.

I have started this process and will create a PR as soon as I am done.

I have been doing some testing on the backend, because we are still trying to figure out how to incorporate the changes to pySAS into the main git repo for SAS. There are some unexpected issues that we are still trying to figure out.

It's only in the last few years that they started using git to keep track of changes to SAS and they just barely migrated to hosting the code on Bitbucket in a private repository. There were some choices made more than 20 years ago in how the code is maintained and compiled that are currently making things very difficult. Everything is being put into a Docker container and there is some question about how the repository here on GitHub will work inside of that. There are issues with how the uncompiled code (including the Python code) is organized in a SAS development environment that makes integration of the new changes to the Python part of the code difficult.

Ah, alright, that makes sense. Let me know if I can help in any way.
