Simple integration test between CARFAC and SAI.

The interface between the two classes is pretty clunky because of the
way CARFACOutput stores things.  We should work on this, probably by
rotating the outer two dimensions of CARFACOutput (i.e. store outputs
in containers with sizes n_ears x n_samples x n_channels instead of
n_samples x n_ears x n_channels).
