Return a local iterator providing modifiable access to the first `value_type` object in the sequence of `value_type` objects of the bucket having the specified `index` in the array of buckets maintained by this unordered map, or the `end(index)` iterator if the bucket is empty. The behavior is undefined unless 'index < bucket_count()'.
