Title: Export iterator/3 so users can iterate over just keys

I've been playing with leveldb iterators (not through `eleveldb:fold`), and would find it useful to be able to iterator through keys only. I don't know if there's a better way to deal with the 3rd argument to `iterator` only being able to be `keys_only`. If you pass in some other atom, it doesn't blow up, but just silently ignores that arg.
