[WIP] Vectorized tess-point in Python

[christinahedges]

Hi @christopherburke, this is a first PR to make tess-point a faster tool that's easier to use in Python. This is absolutely a work in progress (WIP) and there's lots missing from this PR right now! At the moment there is functionality to go from Pixels -> RA/Dec, and not the other way around. I need to implement that!

This PR has big changes to the API, and so I incremented the major version number. I changed the package structure around to make it easier to maintain, and added the first test of a few.

I'll open this now, and we can talk here about how to move forward!

To Do

• Add docstrings and comments
• Implement star_in_fov, optics_fp, make_az_asym, mm_to_pix, radec2pix
• Add functions tess_stars2px_reverse_function_entry and tess_stars2px_function_entry with deprecation warnings
• Ensure command line functions work
• Ensure WASM functionality is included

I am fine with merging the work in progress additions that are currently located in sub directories. Currently, setup.cfg and setup.py are deleted and I am unfamiliar with the pyproject.toml format as well as the purpose of the poetry.lock file.
Will your code work if keep setup.cfg and setup.py for now and remove poetry.lock and pyproject.toml files?
