Review Comment:
   If the contract is that this should produce an iterable, I wonder if we should avoid materializing the list by returning a generator?

Review Comment:
   What I'm suggesting is that we could avoid materializing a list between here and there by returning a generator (`(PredictionResult(x, y) for x, y in zip(batch, predictions))`) here. It looks like that would be undermined by the base DoFn materializing a list again here anyway: https://github.com/apache/beam/blob/68b9100db4b82196eba025bd417c46d03656f7c0/sdks/python/apache_beam/ml/inference/base.py#L198
