Added new protocol and increased packet size

Added a new protocol for the Kambrook remote power sockets.
These use a different protocol to the three currently supported.
They also have a 47 bit packet necessitating the increase of the packet
size from 32 to 64 bit (from unsigned long to unsigned long long).
Updated example to show 64bit packet data
Updated SendDemo example to 64bit

Example to show sending using a 64bit binary value.
