Improve CW decoding process
...
Our approach exploits the autocorrelation properties of the CW signal.
Thus low, high or band pass filtering greatly affects the performance of
the algorithm, because they introduce autocorrelation.

Finish the CW encoder

The CW encoder is a debug block that can be used to check the
performance of the CW decoder of gr-satnogs module under different RF
conditions. It can also serve as a perfect debug tool for sattelite
missions.

Remove CW matched filter block
...
CW decoding using match filtering is pretty much useless in LEO.
The information about the tone frequency is very rare and carrier
oscillations during the satellite pass reduce significantly the
performance.
The new next CW decoder is based on the autocorrelation of the received
signal.
