TI-Basic script thing

TODO: add description here

Features

works
cool preprocessor
- allows you to use comments
- trims unnecessary whitespace for decreased file size on the calculator

migrate to pyproject.toml
either package tilp2 (https://github.com/debrouxl/tilp_and_gfm/) for nix or get rid of my dependency on it by using one of the TIlibs libraries directly. Or since that's only a single feature of the script, I should detect which "install" methods are available at runtime? Or just fail in a "nicer" way if the binary isn't in PATH (ie: we fail with command not found error 127)

add flags to disable/enable each preprocessor feature
add flags to disable/enable all preprocessor features at once
- allows user to disable all, then enable one rather than having to disable all but one individually and vice versa
trim spaces after commas (in function or command param list)
- ex: Input "foo", F -> Input "foo",F (since the latter runs while the former doesn't)
trim spaces around operators (+, -, ->, =, etc.)
grab tokens from token list and create list of tokens that end in a space
- ex: Pause won't work without that trailing space
- after doing that, figure out if I should warn when encountering a token that might've been intended to have a space after it or just fix it and add one
