Convert a event from its journal model to the applications domain model. One event may be adapter into multiple (or none) events which should be delivered to the org.apache.pekko.persistence.PersistentActor. Use the specialised org.apache.pekko.persistence.journal.EventSeq#single method to emit exactly one event, or org.apache.pekko.persistence.journal.EventSeq#empty in case the adapter is not handling this event.
