JsonRpc(

            Error("unknown variant `witness_v1_taproot`, expected one of `nonstandard`, `pubkey`, `pubkeyhash`, `scripthash`, `multisig`, `nulldata`, `witness_v0_keyhash`, `witness_v0_scripthash`, `witness_unknown`", line: 1, column: 1580),

To keep the library future-proof, add Unknown(String) and implement a custom parser, such that if enum variant was not found, then fallback to Unknown(String).
