Return a pair of iterators providing non‐modifiable access to the sequence of `value_type` objects in this map whose keys are equivalent to the specified `key`, where the first iterator is positioned at the start of the sequence and the second iterator is positioned one past the end of the sequence. The first returned iterator will be `lower_bound(key)`, the second returned iterator will be `upper_bound(key)`, and, if this map contains no `value_type` objects having keys equivalent to `key`, then the two returned iterators will have the same value. Note that since a map maintains unique keys, the range will contain at most one element.
