Add 'unlocking_bytecode_hex' and 'locking_bytecode_hex' computed fields

[mainnet-pat]

With these computed fields we now can flexibly lookup/constrain various unlocking and locking bytecodes with custom matches.

Most basic usage:

...
where: {
  inputs: {
     unlocking_bytecode_hex: {_like: "41%9c"}
  }
  outputs: {
    locking_bytecode_hex: {_like: "6a%"}
  }
}
...
