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.

...
The FSK receiver of the CC1120 can now retrieve the frame that is
transmitted over the air. The next step is to provide the support for
data whitening and Manchester coding.

After managing to successfully receive raw bytes from the TI devboard
with the CC1120, its now time to pack them into a frame by searching for
the preamble and synchronizing with the known byte sync word.
