Rewrite CLI using Typer

It's nice

New docs: https://eradiate.readthedocs.io/en/typer/src/reference_cli.html
vs old: https://eradiate.readthedocs.io/en/v0.23.1/rst/reference_cli/index.html

Sectioning is better but can be further improved. We get rid of sphinx-click and can better customize the CLI documentation, so it's overall an improvement.
