Auto-sort commands

[peterbe]

Is your feature request related to a problem? Please describe.

We keep adding .command("foo").argument("...").action("...") to the bottom of the program.
Would be nice if --help could sort all the commands alphabetically.

Describe the solution you'd like
program.help({sort: 'alphabetically'}) perhaps

Describe alternatives you've considered

Manually re-arrange the blocks of .command("foo").argument("...").action("...").

I'm relying on Caporal preserving source order in my own API, so that I can group commands into meaningful categories: https://gltf-transform.donmccurdy.com/cli.html ... so I just wanted to request that if this is supported, using source order remains available as an option.

Related, I wish I could use source order for sub-command options, but alphabetical order is currently enforced there. (#191)
