a  Generates pink noise using the Voss-McCartney algorithm.

    size: either a tuple of int or an int. If an int : number of sample to generate. If a tuple: shape of the return array.
    ncols: number of random sources to add. Should be high enough so that num_samples*0.5**(ncols-2) is near zero.
    axis: axis which contains the sound samples. Generate white noise otherwise.

    returns: NumPy array of shape size
