Prepare a QRC721 token collection transaction for signing

Transforms a transaction request ready to be signed and returns a request ID for executing. The supported transaction types are “Approve Asset Collect” and “Collect Asset”.

• The “Approve Asset Collect” transaction type will allow you to approve someone to subsequently make a transaction that takes the NFT from your address into their own.
• The “Collect Asset” transaction type will create the transaction to pull the approved NFT from an account into the receiving account.
  
  
  Successfully prepared transactions can then be executed using the /execution/transaction API.
