Niccolò Izzo 4b498689f5 Replace RRC filter taps, update M17 testsuite 
RRC filter taps have been replaced with the ones generated by Wojciech,
a new baseband for the M17 demodulation testsuite has been generated,
using OpenRTX itself and some further minor changes.

Niccolò Izzo 3163dd49d7 Add M17 demodulator code and tests 
Added implementation of the M17 4FSK demodulator, including clock
recovery, phase detection, and quantization algorithms.
A testsuite is also included to do regression testing against a
reference baseband pre-generated and the corresponding reference
bitstream.

A 1% BER is still present due to a fault likely in the RRC filtering,
since the eye diagram of the filtered stream is bad.

Niccolò Izzo 6588a6718e Add M17 namespace in M17 related source files 
Now M17 source files reside in the M17 namespace, the OPMODE_ prefix
was added to all opmode enums to avoid a name clash.

Niccolò Izzo 876cb87d57 Move rrc filter into separate compilation unit 
By moving the rrc filter into a separate compilation unit with its own
header file, we can use it both in the modulator and in the demodulator.
