Improvements to Commander Framework Adapter

[shadowspawn]

I recently discovered tab has an adapter for Commander. Cool!

I can see some opportunities for making more use of built-in Commander functionality instead of reverse engineering (e.g. option flag parsing), and improving the integration (e.g. making sure .parseAsync() is also supported). Would you like me to open issues first, or go straight to Pull Requests? My intent is to offer changes in reasonably small PRs for consideration, not a mega PR.

Hey @shadowspawn !
Thanks for opening this issue.
Yeah, the Commander adapter is a bit trickier than the other adapters we have and probably has a few rough edges, so I would really appreciate the help!

Would you like me to open issues first, or go straight to Pull Requests?

I'm totally fine either way, but if you already have a clear fix/improvement in mind, feel free to go straight to PRs and open issues for bigger behavioral changes or discussions.
