Subject: [PATCH 1/3] Update wp_scalogram.py

In the second plot, updated Fs to 512;
`ax2.specgram(data, NFFT=64, noverlap=32, Fs=512, cmap=cmap,
             interpolation='bilinear')`

again in the second plot, added aspect='auto', and did corrections to the time (x axis) and y axis (scale) with `extent=[0, 1, 1, values.shape[0]]`

ax3.imshow(values, origin='lower', extent=[0, 1, 1, values.shape[0]],
           interpolation='nearest', aspect='auto')
