Support BCH full node JsonRpc gateway

Heads up, BCH will soon have proper native UTXO tokens (dual-currency outputs, BCH + token payload)

Should be activated in May '23, early testnet4 already running: https://t.me/cashtoken_devs/2031

@A60AB5450353F40E Thanks for the heads up. Took a quick look over at https://gitlab.com/bitcoin-cash-node/bitcoin-cash-node. Have any nodes started documenting this behavior in the JsonRPC specs?

[A60AB5450353F40E]

It's still like early alpha, still many TODOs, expect an "official" node release (v25.0.0) in November.

testnet4 has been forked using a build off this MR: https://gitlab.com/bitcoin-cash-node/bitcoin-cash-node/-/merge_requests/1600 so people eager to experiment with and test new features can do so

token-related jsonRPCs was added literally yesterday

           "amount": amount,         (numeric or string, required) The amount in BCH
           "tokenData": {            (json object, optional) Optional CashToken data to add to this output
             "categoryId": "hex",    (string, required) The token id
             "amount": n,            (numeric, optional) The token fungible amount
