Return related transaction to public keys in API
The browser currently allows you to work backwards from a decoy output to the transaction that it is created in. This is not possible when using the API. The API presents the "block_no" and "public_key." While I can query the block for the list of transactions and build a local database to see which transaction matches the public key, I would rather the API return the transaction that the public_key is associated with like in the web version. This would save me multiple API requests when trying to work backwards from decoys.
