Requirements

• Caller of the method must attach a deposit of 1 yoctoⓃ for security purposes

• approval_id is for use with Approval Management, see https://nomicon.io/Standards/NonFungibleToken/ApprovalManagement.html
• If using Approval Management, contract MUST nullify approved accounts on successful transfer.
• TODO: needed? Both accounts must be registered with the contract for transfer to succeed. See see https://nomicon.io/Standards/StorageManagement.html

Arguments:

• receiver_id: the valid NEAR account receiving the token
• token_id: the token to transfer
