Add AX.25 encoder that supports the legacy hardware radios
...
The new encoder now supports NRZI and G3RUH scrambling that makes it
compatible with most of the FSK9600 modems.
Remove also some unneeded blocks.

Implement the whitening and de-whitening process for the UPSAT
...
The data whitening and de-whitening mechanism is implemented using
lookup tables for fast processing times. The implementation is quite
generic and modular supporting user defined polynomial masks and seeds.
The lookup table is created during the initialization without any
runtime overhead.

Fix the doppler correction mechanism
...
The doppler correction mechanism has successfully passed the first tests
using the GPredict software for the radio control. The corrections seems
to be quite smooth. The next step is to apply it at an audible signal.
