Subject: remove grmtools

the parser using grmtools was way oversized for just doing escape
sequences, and only really existed since I wanted to play around with
it.

The new implementation depends on no external crates, uses just an iter
wrapped into a nicely composable function, and appears to be exactly
equivalent (but faster).
