Add computation of the AD for different freq ranges
This computes the AD for various frequency ranges, specifically fmin to srate/2^N, down to srate 256. So for a run with srate 1024, it will compute the print ADs for srate 256, 512, 1024. This is an example output
Seglen8/srate1024_V $ cat post/clean/glitch_anderson_darling_V1.dat 1024 0.868554 0.434127 512 0.650899 0.601219 256 0.373333 0.874708
First column is the srate, second column is the AD, third column is the p value.
