The implementations for the fully connected layer can be simlpified by using `VectorMath:DotProduct()`. In this way, it is also possible to remove (nearly) duplicated SIMD code, reduce the binary size and more easily maintain the code. This CL also forces unoptimized code for the output layer of the VAD, which is a FC 24x1 layer. A slight improvement of the realtime has been measured (delta ~ +5x).
