nomnom is no longer supported and generates security vulnerabilities

[domenic]

Just an FYI: https://www.npmjs.com/package/nomnom says "This package has been deprecated", and running npm audit generates various security vulnerability warnings.

I am sure none of them are actually exploitable, so it's not a big deal. But I thought maybe you would want to have an issue on the record for moving to a supporting command-line arguments processor. (I tend to use yargs but Node 16+ has a built-in parser that might work.)

@domenic thanks, yes, we'll need to migrate to the modern approach used today for this (both yargs and native Node should work). Would appreciate a PR in case.
