Save sonified audio at 16-bit instead of 64-bit #141

Minor thing but with sonify_bounds set, the extra output audio file is really large (a 5 minute music track is around 60 MB even at only 22.05 kHz).

Reason is scipy.io.wavfile.write respects the dtype of its input array, which is always doubles in NumPy when left unspecified.

This PR adds the bit depth conversion from scipy.io.wavfile.write's docstring (60 MB -> 15 MB).

Nice catch! Merging it...
