Sylvain Munaut f5bdb26c94 utils: Import some utilities to actually receive and process signals 
This includes an utility to easily identify what ARFCNs are visible in
a given capture made by osmocom_fft and a utility to do live captures
using GNURadio.

Sylvain Munaut 9eb01d12b1 sdr/pix4cxpsk: Improve frequency error estimation/tolerance 
- Combine power of correlation chunks rather than the complex value
   (since for long burts, the chunks might have quite a bit of
    phase error and this throws off alignement)

 - Use difference of phase between consecutive chunks and not wrt
   to the first chunks since it might drift more than pi.

Sylvain Munaut a23f3d3243 sdr/pi4cxpsk: Add a method for modulation of pi/4 CxPSK bursts 
This currently only supports 1sps. To upconvert, it should be
convoluted with a RRC filter.

It required adding a second table of symbol in the modulation
type where the entries are sorted by the 'bits' value rather
than the symbol number.
