Better handling of unions of literals/enums

It would be good to have a Runtype for Enum that could take an existing TypeScript enum and return a type for validating it.
It would also be possible to optimise unions of literals by generating a Set<string | number> up front to allow O(log(n)) lookup instead of linearly traversing the list. It might also be worth adding some form of caching to show.

It should be able to handle cases where unions are nested and cases where one entry in the union has multiple possible literal values for a tag
