Added a noise gate based on signal power: if the normalized signal power
is less than -40dB, the original incoming singal is not encoded.
This feature is activated by the CONFIG_CODEC2_NOISE_GATE macro.

Added implementation for a power-based squelch equivalent to the GnuRadio
"Power Squelch" block. The envelope filter is implemented using signed
32-bit fixed point math.

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.

New DC block filter implementation using fixed-point math and guaranteeing
zero DC component on the output signal.

Added the ability to manage CTCSS enablement via the FM settings menu.
As part of this, refactored the existing instances of setting and
displaying this value on the main vfo screen and on the macro menu.

This seeks to create a place for settings on the FM mode that complement
the quick actions available from the macro menu. This way as more FM mode
features are added, there is a menu to configure them in.

This change makes it so that the macro menu shows the current tone and
change the tone setting with macro 1, then change tone frequency with
macro 2 and 3. This is a clearer UX.

This change makes it so that CI/CD builds against all supported platforms,
utilizing the devcontainer as its environment rather than setting up one
separately. This allows to have the CICD builds and dev local builds more
similar and reduces the maintenance overhead.

This change makes it so that the devcontainer in this project is able to
build and wrap all supported platforms. There is a pre-existing issue on
arm64 devices preventing the openrtx_gd77_wrap and openrtx_dm1801_wrap
targets from working, which is being tracked in
https://github.com/OpenRTX/OpenRTX/issues/344.

Once the RTC has been synchronized with GPS time, set the gps_set_time
flag back to false. This resets also the corresponding ON/OFF menu entry,
providing both a feedback that the operation is done and allowing the user
to just set it back to ON in case a new synchronization is needed.
Clearly show on UI the case when no GPS receiver has been detected in the
hardware. Previously either the "GPS off" or "No fix" strings where shown
also in case of no GPS, causing ambiguity.
Added function to retrieve the clock frequency of the bus a peripheral is
attached to, given its base address. The function is C++ only and relies
on constexpr mechanism to have zero memory footprint.
Added implementation for a lock-free ring buffer designed for storage and
retrieval of full NMEA sentences. Data can be inserted either by char or
by sentence and extracted only by full sentences.
The size of the buffer, in byte, is defined via the CONFIG_NMEA_RBUF_SIZE
macro.
