(.Acquisition_1C.use_CFAR_algorithm=false) as an option in the

the presence of non-gaussian front-end noise (which is the usual
behavior of front-ends....)

Javier Arribas 4480c12d94 Added a non CFAR PCPS acquisition algorithm based on the estimation of
the post correlation noise floor. If enabled

Cillian O'Driscoll 5b9683baad Multiple changes pcps acquisition: including linear corr.
Reduced zero_padding_factor in pcps acquisition

This was 16, I'm processing data at about 16MHz, this oversampling
factor caused memory allocation issues

Previously dump file name was not being read from the configuration

Added fix for non-zero IF in pcps_acquisition_cc

Added linear correlation to pcps acquisition.
