Redesign of the AX.25 decoder
...
This commits introduces a significant redesign of the AX.25 decoding
block. Due to the poor AX.25 sync flag, the decoders exhibited too many
false alarms. To deal with this problem, we introduced the quadrature
demod filter block, that tried to measure the SNR based on the running
variance of the signal. The problem with that was that the user should
have to fine tune two parameters, the one related with the amplitude of
the incoming signal and the second one related with the window that the
calculations should take place. This solution worked until now, but we
can always increase the performance.
The new AX.25 decoder stores the bitstream in a queue and always tries
to exlpoit possible valid frames in the queue. If now sync flags have
been encountered, the queue is flushed. After a valid frame extraction,
bits corresponding to this frame are also deleted from the queue.
This technique requires more memory and CPU, but it increases a lot the
decoding performance.

Add VCO-based frequency correction
...
This commit includes a blind frequency correction mechanism for FM
signals. It uses the information of the angle difference between two
concecutive samples and a VCO to continuously compenstate any frequency
offset. To avoid intermodulations, a low pass filter is used trying to
pass only the DC component that is needed.

Improve CW decoding
...
* Introduce the hysteresis option, in order the CW demodulator to adjust
properly the plateau length based on the WPM and any filtering that can
be used before
* Instead for a frame per word, now the CW decoder waits for 10 long
spaces before it commits a frame. With this way many words are placed on
the same frame telemetry decoding is easier
