> when using PubsubIO.writeProtos(protoMessage), the PubsubMessage is created in the background and there is no way to specify the attributes of the message. This makes the method useless if a user wants to then use the withTimestampAttribute() or withIdAttribute() of the writer with anything other than the default timestamp or ID (a common use case).
> As a workaround the user can manually create the PubsubMessage, but this basically requires duplication of the writeProtos() logic, which is brittle in the case that the encoding logic changes.
