Hamster::Hash#merge

Return a new `Hash` containing all the key/value pairs from this `Hash` and
`other`. If no block is provided, the value for entries with colliding keys
will be that from `other`. Otherwise, the value for each duplicate key is
determined by calling the block.

`other` can be a `Hamster::Hash`, a built-in Ruby `Hash`, or any `Enumerable`
object which yields `[key, value]` pairs.
