Investigate Cyclopts as alternative to Typer

[onyx-and-iris]

Typer is slow due to rich module imports, see Lazy-load rich_utils. This has already been fixed in cyclopts, see defer rich import until needed.

I'm not getting faster times with cyclopts unfortunately although I prefer some of the approaches it takes. However, I will stick with Typer and hopefully the rich lazy loading fix will get merged at some point...
