change serialization / deserialization for OneEraGenTxId so it's treated as a bytestring and is decoded into an arbitrary era

use PatternSynonyms rather than coerces for ByronDlgId / ByronUpdate*Id

use Shelley for blessedGenTxIdDecodeEra for CardanoShelleyEras

OneEraGenTxId { NS WrapGenTxId xs -> ShortByteString }

use CardanoNodeToClientVersion15 instead of creating a new version

move GenTxId to its own section and describe why it's not an NS of GenTxId
