Polarity preserving decon in ``N log N'' time
A slight modification to Fourier spectral factorization
enables deconvolution to preserve and enhance
It spikes the center lobe of the Ricker wavelet.
It works by tapering at small lags
the antisymmetric part of the time-domain representation of the log spectrum.
