Review comment:
It was insisting I place the protobuf import prior to the beam imports, but
then if I did that, complaining about the grouping with the pubsub import.
However, as mentioned above, I didn't realise you could nest imports in a
try/catch, so this should resolve this.

> Looking at the source code, with my untrained python eyes, I think if the

> """Construct from serialized form of ``PubsubMessage``.
> Args:
> proto_msg: String containing a serialized protobuf of type
> https://cloud.google.com/pubsub/docs/reference/rpc/google.pubsub.v1#google.pubsub.v1.PubsubMessage
> Returns:
> A new PubsubMessage object.
> """
> msg = pubsub.types.pubsub_pb2.PubsubMessage()
> msg.ParseFromString(proto_msg)
> # Convert ScalarMapContainer to dict.
> attributes = dict((key, msg.attributes[key]) for key in msg.attributes)
> return PubsubMessage(msg.data, attributes)
> The protobuf definition is here:-
> https://cloud.google.com/pubsub/docs/reference/rpc/google.pubsub.v1#google.pubsub.v1.PubsubMessage
> and so it looks as if the message_id and publish_time are not being parsed as
> they are seperate from the attributes. Perhaps the PubsubMessage class needs
> expanding to include these as attributes, or they would need adding to the
> dictionary for attributes. This would only need doing for the _from_proto_str
> as obviously they would not need to be populated when transmitting a message
> to PubSub.
> My python is not great, I'm assuming the latter option would need to look
> something like this?
> attributes = dict((key, msg.attributes[key]) for key in msg.attributes)
> attributes.update({'message_id': msg.message_id, 'publish_time':
> msg.publish_time})
> return PubsubMessage(msg.data, attributes)
