Pooltool: A Python package for realistic billiards simulation

What's Changed

• README has been overhauled
• Docs have been overhauled (https://pooltool.readthedocs.io/en/latest/), and now support an Examples section of rendered notebooks
• Installation instructions are clear and simplified
• Test files no longer exist in the package, and are found in a mirroring directory tests
• Event caching speeds up simulation times considerably: https://github.com/ekiefl/pooltool/pull/133
• Numba functions are compiled when the user first enters the interactive interface. A corresponding translucent menu now pops up
• Add deflection angle physics (squirt): https://github.com/ekiefl/pooltool/pull/139
• The ShotViewer class has a new abstraction, pooltool.show and window management is automatically handled. No more idle window when there is nothing being visualized.
