      Added two layers to apply random scaling or random shift for tensors of standardized shape BWHF (Batch, Width, Height, Features).
      When training is False, the layers do not apply random scaling or shifting. However, the random shift layer still apply a right zero padding to ensure that the shape of the layer output is identical during training and testing.

      Added a bank of 20 Gammetone filters, of 512 coefficients and sampling rate 44100hz, covering the frequency range 100-20000hz. Filters are windowed with the right half of a Hann window (of size 1024).

      Added a script to generate Gammatone FIR filters in .wav format, by using the library from Bingo Todd.
      Because a rectangular windowing produces ringing in the magnitude of the frequency response at low frequencies when the filter have ~512 coefficients, we apply a windowing of the filter impulse response in order to improve the filter quality. After windowing, a normalization is applied to restore the correct magnitude peak in the frequency response domain.
