Feature Request: Subcommands and Nesting

[khill-fbmc]

First off, love this library, primarily for the REPL features. I keep eyeing Clipanion since it seems like it is designed to be used as a multi-command, nested type of program. I like that, but then I loose my nice REPL features you've added.

This is what I have setup so far, (match is from ts-pattern)

It works, but does not feel very scalable. Is there a better approach to make nested type commands?

Nested command can be added like this:

program()
  .add(
    command("session")
      .add(
        command("start")
          .action(() => console.log("start"))
      )
      .add(
        command("stop")
          .action(() => console.log("stop"))
      )
      // and so on...
  )
  .run();

Hope this helps.

If you have any ideas how to improve this for your use case, I'm curious to hear!
