Changes to prepare for package release

[cgobat]

This is a draft PR to track the status of updates in preparation for packaging and release, as discussed in #15.

Current status on this branch (cgobat/tetra3@package_prep) is as follows:

• [x] The current API and installation method needs to not be broken
• [x] Update docs for readthedocs deprecation of "use system packages"
  • [x] Add .readthedocs.yaml file (cgobat/tetra3@65b19c0f9130060f1f6c443c7887121875211b87)
• [x] Change the directory structure to be more typical (cgobat/tetra3@f82066d74a5c9eaa71cbf72527774ff5428e32bb)
• [x] Remove all but one or two example image from master to save size (cgobat/tetra3@155a529492c22a2589417c544e1c6f3894c8d5f3)
• [x] Make sure the logs go somewhere sensible, or perhaps disable by default (cgobat/tetra3@7a0acbe2d90735bd15af33753d30645d7fe62428)
• [x] Set version to 0.1 (cgobat/tetra3@f82066d74a5c9eaa71cbf72527774ff5428e32bb)
• [ ] Set up PyPI to publish on pip

I will update this list as more progress is made.

I've made it so the git repo can be used as the tetra3 module directly by adding an __init__.py file (that was the current installation method not to break), and moved the package data and test data to respective subdirectory

[gustavmpettersson]

I think readthedocs.yaml should work, we'll find out when the PR is merged so I can set up a build on that branch. PyPI we can do after the release is up on github.

I think this is ready, can you test on your end?

[cgobat]

Yes, things seem to be working on my end. I just ran a remote pip install git+https://github.com/cgobat/tetra3@package_prep on a completely fresh system and everything installs as expected.

[gustavmpettersson]

I've gotten the docs to build now. I'd just like a new installation section (basically, I want to get rid of all the conda stuff. It was copy pasted from a different package I wrote that has difficult dependencies), then it should be able to go to master.

[gustavmpettersson]

I've pushed to master and no_big_files. Seems to work well, and I've improved the documentation. It appears we have to migrate from setup.py to pyproject.toml to build a PyPI version, so I'll deal with that later
