New sounds for SCP mob

Because spooks deserves top quality spooking

Intended to be 3 kill sounds and 4 sight sounds

Taken directly from the remix taken directly from an SCP game. Since it's custom sounds I found on a TF2 server, I'm going to play it dangerous and say I can just take it as is
Also, I have noticed the sounds seem to play multiple times in one tick and snaps a target's neck twice. It doesn't cause any problem other than double adminlog messages and ear straining, but I'm warning ahead of time
