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.

Finish the AX.25 decoder and add a UDP message source block
...
The AX.25 decoder is now decoding the received frames.
Also, the module now provides a UDP message source block. This block
will be responsible to receive UDP packets and transform them into PMT
messages for further processing in the GNU Radio flowgraph. As the
communication with the satnogs-client will be done in the same host, we
do not have to care about packet loss.
Furthermore, the module now provides and a debug message source block
for easy debugging.
