Return a JSON object representing the serialized, hex-encoded transaction.
Argument #1 - hexstring Type: string, required The transaction hex string
Argument #2 - iswitness Type: boolean, optional, default=depends on heuristic tests Whether the transaction hex is a serialized witness transaction. If iswitness is not present, heuristic tests will be used in decoding. If true, only witness deserialization will be tried. If false, only non-witness deserialization will be tried. This boolean should reflect whether the transaction has inputs (e.g. fully valid, or on-chain transactions), if known by the caller.
