#packet_protocol ⇒ ShadowsocksRuby::Protocols::SomePacketProtocol

Packet Protocol

A Strategy Pattern for replacing protocol algorithm

all read from ShadowsocksRuby::Connections::BackendConnection‘s #packet_protocol is just data,

the first send to #packet_protocol chould be address_bin (for a RemoteServerConnection) or data (for a DestinationConnection), other send to #packet_protocol should be just data
