Created a CI workflow for building wheels on linux

[MicahGale]

This is related to #9.

This workflow simply:

1. for all PRs and pushes to main runs this job
2. Goes through installation process
3. Creates a python wheel and source distribution for python 3.9 - 3.13
4. Uploads these are build artifacts.

These artifacts will be temporary (~1 month), and does not help with creating github releases. See example here.

Help would still be needed for windows and mac.

Note:

Github actions would need to be enabled on this repository.

Not realizing that you had already done this, I made a different PR (#16). Mine should work for Windows. Maybe we can find a way to combine them? And then find a collaborator for mac.

Oh nice! You have a pretty good setup. If you want I would be ok with you merging my branch into yours. Though I may keep this PR open until something actually happens.

I just discovered that this process doesn't include any LICENSE files in the wheel, which should generally be done. @msaitta-mpr Here's a guide on including those files. It would be a good idea probably for the license to be moved/duplicated into its own LICENSE file, but that probably should come from a LANL maintainer.
