4480c12d94 Added a non CFAR PCPS acquisition algorithm based on the estimation of 
the post correlation noise floor. If enabled
(.Acquisition_1C.use_CFAR_algorithm=true) as an option in the
acquisition configuration, it allows setting more stable thresholds in
the presence of non-gaussian front-end noise (which is the usual
behavior of front-ends....)

db321d1c2e Fixing missing phase increment in SIMD implementations 
After computing the rotation with SIMD instructions, we were not
incrementing the phase step, so the first iteration in the 'c region'
had the same phase than the last sample computed with SIMD instructions.
This commit fix the bux in SSE3 and NEON implementations
