Create a python package

GIVEN that some of my notebooks contain things I want to run regularly
WHEN I run pip install anger-local-beehive (or poetry install or conda?) into a virtual environment
THEN I have access to command-line utilities that allow me to perform the specific tasks that were prototyped in the notebooks
SO that I don't have to spin up Jupyter and run through a notebook every time I want to do that thing

Some examples:

• Finding a specific mob by species, owner, name or nbt property
• Creating a Creative Mode copy of a world
• Locating unopened loot chests
• Getting the ore composition of chunklets

(TODO: make separate issues for each of these, but they're all blocked by this issue, so...)

Sub-tasks

• create package structure (pip installation is a must-have, poetry would be sugar)
• research options for auto-versioning that wouldn't bump versions on changes to the notebooks (I think I can do this while keeping everything in one repo using worktree)
• set up HTML docs, explicitly to include notebooks (sphinx had a plugin for this, I would be super surprised if mkdocs doesn't have a wrapper for nbconvert as well)
• unit tests (am I going to need to create a testing world?)
• CI via github actions
• onboard to PyPI
• CD via github actions

Start by reviewing the linked notebooks and the package, documentation, testing, GitHub Actions, PyPI, and release sub-tasks. The scope includes turning notebook prototypes into installable command-line utilities, with HTML documentation and automated delivery. Done means the package can be installed and the listed notebook tasks are available through utilities without launching Jupyter.
