RakNet protocol bug

There is a bug in RakNet that has caused login to fail on certain protocol implementations such as https://github.com/MarfGamer/JRakNet where NewIncomingConnection (0x13) encodes the packet incorrectly. This causes the addresses to read incorrectly, causing an underflow as there aren't enough bytes in the packet. This underflow occurs because the version (this first unsigned byte) is 254, causing the packet to read 254 bytes when the actual size of it is less than 140. This version affects STRICTLY Windows 10 edition, and does not occur on mobile.
