A Protocol Buffers based serializer for DurableEvents.
Serialization of DurableEvent's payload is delegated to BinaryPayloadSerializer.
To use this serializer the default config provided by reference.conf has to be overwritten in an
application.conf like follows:
akka.actor.serializers.eventuate-durable-event = com.rbmhtechnology.eventuate.serializer.DurableEventSerializerWithBinaryPayload
This serializer can be useful in scenarios where an Eventuate application is just used for
event forwarding (through replication) and only handles the payload of events
based on their metadata (like the manifest).
