Return a pair of iterators providing modifiable access to the sequence of `value_type` objects in this unordered multiset equivalent to the specified `key`, where the first iterator is positioned at the start of the sequence, and the second is positioned one past the end of the sequence. If this unordered multiset contains no `value_type` objects equivalent to the `key`, then the two returned iterators will have the same value.
