Validate NFT Order

Loopring L2 supports a method for validating one side of an NFT order. NFT order validation is not required for Loopring, but when making an NFT trade, it should pass this validation

// Step 1. getAccount
const {accInfo} = await LoopringAPI.exchangeAPI.getAccount({
  owner: LOOPRING_EXPORTED_ACCOUNT.address,
});
console.log("accInfo:", accInfo);

// Step 2. eddsaKey
const eddsaKey = await signatureKeyPairMock(accInfo);
console.log("eddsaKey:", eddsaKey.sk);

// Step 3. apiKey
const {apiKey} = await LoopringAPI.userAPI.getUserApiKey(
  {
    accountId: accInfo.accountId,
  },
  eddsaKey.sk
);
console.log("apiKey:", apiKey);

// Step 4. storageId
const storageId = await LoopringAPI.userAPI.getNextStorageId(
  {
    accountId: accInfo.accountId,
    sellTokenId: LOOPRING_EXPORTED_ACCOUNT.nftTokenId,
  },
  apiKey
);
console.log("storageId:", storageId);
// let hash: any = new BN(nftId,'hex')
// hash = toHex(hash);//new BigInteger(sha256(nftId.toString()).toString(), 16)

// Step 5. submitNFTValidateOrder
const response = await LoopringAPI.userAPI.submitNFTValidateOrder({
  request: {
    exchange: LOOPRING_EXPORTED_ACCOUNT.exchangeAddress,
