Add CLI documentation

[CasperWA]

New CLI.md document in the root of the docs folder with a complete API documentation of the CLI.

New pre-commit hook using the locally installed typer to auto-generate the CLI documentation.
Not reasonable as it apparently takes two runs to generate the proper documentation.

---

To do:

• Update the new CI job with some helpful messages.
