Description

We're trying to add a Dataflow template for Pubsub -> BigQuery where the Pubsub topic contains serialized proto data. This is similar to our existing template for Pubsub -> BigQuery using Avro.

However, it seems the PubsubIO currently only supports protos where the class is known.[1] We'll need something similar to the generic Avro reader[2].
