## blockchain.utxo.get

Returns data on a specified output of specific transaction. Returns error
if transaction or output does not exist.

If the output is spent, information about the spender is provided. This allows
a SPV client to call `blockchain.transaction.get\_merkle` to generate a merkle
branch, proving that it is spent.
