Review comment:
       As I understand we can't use the result of ATOMIC_TYPE_TO_PRIMITIVE[schema_pb2.BYTES] because it would result in `x = bytes('abc')` which would raise an error?

   Cool! LGTM, but I suppose @robertwb will have more to review.

Review comment:
       That's right. This is basically the same as the logic here:
   https://github.com/apache/beam/blob/3b0ba733dc3d9b063b3fff9297073f26c06e8a0d/sdks/python/apache_beam/coders/standard_coders_test.py#L118-L121
   
   I have a TODO in the code to unify these paths but haven't gotten around to it yet.
