Implement saving and loading of pyFFTW wisdom for substantial speedup

1

As an example, running forward NSGT on `fugue.wave` takes 1s compared to about 180s initially, and `nsgt_test.py` takes 8s instead of 30s on my machine, because we essentially skip over...

assemble_coeffs function in ./examples/spectrograms.py returns error

Observing `c` created on [line 108](https://github.com/kungfujam/nsgt/blob/master/examples/spectrogram.py#L108), I see it generates objects of dimension 1 x 66 (a 2d array) therefore the function complains that the index [2] is out of...

Support pyFFTW along with PyFFTW3

2

I couldn't get PyFFTW3 installed on my machine, but pyFFTW is an alternative wrapper for FFTW that appears better maintained. You can see a speed comparison of the two wrappers...

Very slow cq_test, slicq_test

For example, on Windows10 / AMD64, running `python -m unittest discover -s tests -p cq_test.py` results in tests taking something like ~10-20 minutes to finish. Is this normal?
