docs: Splits a path into the part matching this middleware and the part remaining.
          If path does not exist, it returns a pair of None values.
          If the regex matches the entire pair, the second item in returned tuple is None.
  
          Args:
              path (str): The url to split
  
          Returns:
              Tuple
              matching_path (str or None): The beginning of the path which matches this
                  middleware or None if it does not match
              remaining_path (str or None): The 'rest' of the path, following the matching part
