Missing files in 0.12.0 release (ImportError: cannot import name schema_pb2)

I believe there has been some issue with the packaging because I am getting this error when running a pipeline with tf.Transform and getting the following error that after some investigation led me to tensorflow-metadata

File "/usr/local/lib/python2.7/dist-packages/tensorflow_transform/init.py", line 21, in
from tensorflow_transform.mappers import *
File "/usr/local/lib/python2.7/dist-packages/tensorflow_transform/mappers.py", line 62, in
from tensorflow_transform import schema_inference
File "/usr/local/lib/python2.7/dist-packages/tensorflow_transform/schema_inference.py", line 30, in
from tensorflow_transform.tf_metadata import dataset_schema
File "/usr/local/lib/python2.7/dist-packages/tensorflow_transform/tf_metadata/dataset_schema.py", line 23, in
from tensorflow_transform.tf_metadata import schema_utils
File "/usr/local/lib/python2.7/dist-packages/tensorflow_transform/tf_metadata/schema_utils.py", line 28, in
from tensorflow_metadata.proto.v0 import schema_pb2
ImportError: cannot import name schema_pb2

I checked the files at https://pypi.org/project/tensorflow-metadata/#files and they are indeed missing protos that should be there as per the aforementioned ImportError

Inspect the tensorflow-metadata 0.12.0 files on PyPI and trace the failing import from tensorflow_transform/tf_metadata/schema_utils.py. Confirm that the release includes the generated schema_pb2 module and that importing it succeeds; the issue is done when the published package no longer raises this ImportError.
