incoming/odfi: events should represent an EntryDetail record

[adamdecaf]

Currently our events emitted from Inbound.ODFI assume files represent "corrections" or "returns" and are not comprised of multiple entry types. This isn't the case in most real-world deployments. We should look at emitting events at the EntryDetail level (with their Batch Header) instead.

Events that are broken:

• CorrectionFile
• IncomingFile
• PrenoteFile
• ReconciliationFile
• ReturnFile

Should we create new events with their BatchHeaders?

• CorrectionEntry
• IncomingEntry
• PrenoteEntry
• ReconciliationEntry
• ReturnEntry
