Can read what is in the byte array (converted to hex)

I felt like this was pretty important to note. This can read the packet
from the byte array (by converting the byte array into a hex string).
Writing it out to the console, I saw the
00ffff00fefefefefdfdfdfd12345678, which is equal to MAGIC. Before it,
would be the client id, and the first two characters (01), would be the
Packet ID (PID). The PID SHOULD have been 0x01, and the packet had 01
at the front, so they matched.
