style: resolve ambiguous paths on include macros
...
Update meson and cmake config to only include openrtx and platform paths.
Update files to use <..> for system and external libraries, ".." for
project files and new relative paths as necessary.
Did not attempt to fix areas where includes that should be <..> were
previously ".."
Inspired by #96 , closes #359 .

M17: deeply restructured the demodulator code
...
Restructured the M17Demodulator class and rewritten the
demodulator logic to have a more solid lock on the
baseband stream. This fixes the long standing bug of the
demodulator causing random losses of lock even when
receiving a solid baseband stream.

turn on the radio, remember to turn of radio before you terminate
get_demod_log, print the output with

Switch M17 Rx sample rate to 5SPS
...
Due to the RRC computation sometimes violating the timing constraints,
we switched the M17 demodulator to 5 samples per symbol (24KHz), thus
dividing the processing time by four ar the number of samples halves as
well as the number of taps of the RRC.
Minor adaptation on the code followed.
