update raymath.h function QuaternionMultiply

Browse Source 
the multiplication algorithm was slightly off
previously when combining quaternion rotations objects would shrink
now they rotate as expected

trying to get around the issue by using QuaternionToMatrix then QuaternionTransform doesn't work, and I'm not sure why
