Regex sets permit matching multiple (possibly overlapping) regular expressions in a single scan of the search text. This adds a few new types, with `RegexSet` being the primary one. All matching engines support regex sets, including the lazy DFA. This commit also refactors a lot of the code around handling captures into a central `Search`, which now also includes a set of matches that is used by regex sets to determine which regex has matched. We also merged the `Program` and `Insts` type, which were split up when adding the lazy DFA, but the code seemed more complicated because of it. Closes #156.
