Hi there, `Peg.js` is unmaintained, so I figure you all would appreciate if I replaced it with the drop-in replacement of Peggy. This is work I am breaking out of #918. Peggy adds new features like source map support that we could use, although I do not include that in this change-set. It may be useful for debugging changes to the .pegjs file we have.e
