Return a pair of iterators providing non‐modifiable access to the sequence of `value_type` objects in this unordered multimap with a key 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 multimap contains no `value_type` objects with a key equivalent to `key`, then the two returned iterators will have the same value.
