/**
* This command is supported only by <a href="http://github.com/bitcoinxt/bitcoinxt">Bitcoin XT</a> nodes, which
* advertise themselves using the second service bit flag. It requests a query of the UTXO set keyed by a set of
* outpoints (i.e. tx hash and output index). The result contains a bitmap of spentness flags, and the contents of
* the associated outputs if they were found. The results aren't authenticated by anything, so the peer could lie,
* or a man in the middle could swap out its answer for something else.
