Feature request: ?cmp parameter for PMap.find

Would it be possible to have PMap.find take an optional comparison
parameter? I was just using PMap in some OCaml code and discovered
that, since my keys contain Big_int.big_ints, I need to have a custom
comparator for the one find that I do. It would have been nice to have
that feature built-in.
