"""Removes outer Iterable (or equivalent) from output type.
Only affects instances with simple output types, otherwise is a no-op.
Does not modify self.
Designed to be used with type hints from callables of ParDo, FlatMap, DoFn.
Output type may be Optional[T], in which case the result of stripping T is
used as the output type.
Output type may be None/NoneType, in which case nothing is done.
Example: Generator[Tuple(int, int)] becomes Tuple(int, int)
Returns:
A copy of this instance with a possibly different output type.
Raises:
ValueError if output type is simple and not iterable.
