extends InPacket

 input packet base class 0f 05 series 
 1. packet header sign, 1 byte
 2. source, 2 byte
 3. packet length, 2 byte
 4. packet command, 2 byte
 5. packet sequence number, 2 byte
 6. user QQ number, 4 byte
 7. packet body
 8. packet tail, 1 byte

 noteworthiness is: packet body of this packet is really not full encryption type, but part encryption.
