The maximum number of bytes in a Condition. Xrpld currently caps this value at 128 bytes
(see maxSerializedCondition in xrpld source code), so we do the same here.
The maximum number of bytes in a Fulfillment. Theoretically, the crypto-condition format allows for much larger
fulfillments, but xrpld currently caps this value at 256 bytes (see maxSerializedFulfillment in xrpld source
code), so we do the same here.
The number of bytes in a Public key. In XRPL, ed25519 public keys are prefixed with a one-byte prefix (i.e., 0xED)
to be consistent with secp256k1 public keys, which always have 33 bytes.
