Add a IEEE 802.15.4 like decoder, which supports
the IEEE 802.15.4 standard but also a large variety
of ICs based on this framing scheme. Such framings
are quite common in many Cubesat missions.
The decoder has been tested an works well with at least
the Reaktor Hello World satellite
TODO:
* Use the shift register likewise the AX.25 to get rid off the
quadrature demodulation filter. This will significantly increase the
number of decoded frames
To simplify the logic and allow an easy and more efficient way to add
new decoders, the new architecture uses only one decoder block.
This block takes as input a void* stream and produces PDUs with their
metadata. To do so, the block accepts a decoder object. Every decoder
should implement the virtual class decoder(). This class provides the
necessary API and an arbitrary number of decoders can be supported. The
decoding status is reported to the frame_decoder block through the
decoder_status_t structure.
