Description: switching from yargs to commander would reduce dependencies. commander has 0, yargs has 16

Every downstream dependency adds work as all of them need updates and all of them may have vulnerabilities. Lowering dependencies is generally a win.

If there's nothing special about yargs, would it be ok to provide a PR to remove it and replace with commander?

note: commander is more popular than yargs. Not that popularity has anything to do with quality, only that lots of people are relying on it.
