 // Dumps out the decryptable contents of a QUIC packet in a human-readable way.
 // If the packet is null encrypted, this will dump full packet contents.
 // Otherwise it will dump the public header, and fail with an error that the
 // packet is undecryptable.

 // Usage: quic_packet_printer server|client <hex dump of packet>
