Title: Restrict the fuzzer to the grammar's alphabet

See my comment on the fuzzer PR: https://github.com/airbnb/collapstring/pull/4#issuecomment-37772087

Restricts fuzzing to the alphabet of the grammar and more thoroughly explores the states that depend on rare bigram sequences (relative to uniform choice over all bytes). Branched from your's.
