Hamster::Vector#repeated_permutation

When invoked with a block, yields all repeated permutations of length `n` of
items from the `Vector`, and then returns `self`. A "repeated permutation" is
one where any item from the `Vector` can appear any number of times, and in
any position (not just consecutively)

If no length `n` is specified, permutations of all elements will be yielded.
There is no guarantee about which order the permutations will be yielded in.

If no block is given, an `Enumerator` is returned instead.
