Niccolò Izzo f9c23452bc Add plotting function to graphics library
Added plotting function to graphics library which is native C++, so
refactored the graphics source file to allow that, consequently adapted
the hwconfig header files to be included also in C++ sources.
Propagated compile flags also to C++ sources, including asan what was
previously disabled for C++ compilation units.

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.
