Add arg

[styfle]

This adds arg which is similar to commander and yargs but super tiny.

very cool. whats the selling point of "tiny" in a node app tho?

[styfle]

The same selling point in any app

• less disk space => happy users
• less require() calls => better performance
• zero dependencies => faster npm install
• less LOC => easier to audit and understand

I could go on but this is off the top of my head 🤔

yea the other stuff is more appealing to me than less disk space :) disk space is cheap.
