* Reduce size of the YamlNode structure in FLASH storage.
Fix compiler warning.
* Further reduction of FLASH used by YamlNode structures.
* Reduce size of sensor definition arrays and audio tone volumes array.
* introducing external MLink module telemetry as module PPM subtype
* implemented fix for sensor discovery display not showing all detected sensors (is in separate PR too)
implemented PPM subtypes in Companion
* add PPM subtype to model printer
finalize subtypes for PPM in Companion
* added logic to try to use HW UART with inverters turned off first (e.g. NV14), then, if not successfull use soft serial inverted (== uninverted data due to HW inverters on PCB)
changed start bit detection IRQ priority from 5 to the previous 0 (also in separate PR)
* extended telemetry timeout to 2s due to slow Mlink RSSI update rate
* changed the "NOTLM" sub-type texts to:
- "No Telem" for 128x64 (this is the max numbers of characters it can take)
- "No Telemetry" everything else including Companion
* Companion:
- lower case 1st charachter on PpmSubTypeStrings to ppmSubTypeStrings
- added telemetry hooks for ppmSubTypeStrings stringx
* simplified serial port initialization for MLink telemetry
* editorial change: corrected obsolete comment
* - all telemetry sensor name definitions in one place (untranslated.h)
- all telemetry sensor name definitions follow the naming convention STR_SENSOR_<sensor>
- eliminated one redundant definition
- editorial updates to telemetry protocols code to reflect the naming convention changes
- re-introduced translations in da.h (STR_SENSOR_THROTTLE and STR_SENSOR_SPEED)
- re-introduced translation in it.h (STR_SENSOR_GPSDATETIME)
- re-introduced translation for fr.h ( STR_SENSOR_BATT)
- saved 160 Bytes of flash
* removed obsolete translation
saved 280 byte flash memory in total
* finally removed extern const char STR_MENUTEMPLATES[]; definition
adjusted da.h, fr.h, it.h local sensor name definitions to naming conventions STR_SENSOR_<senosr>
* corrected merge
removed obsolete #ifdef
* some more obsolete ones
* added TW and CN translation for TR_PERIOD and TR_INTERVAL
fixed problem in /radio/src/gui/colorlcd/fullscreen_dialog.cpp preventing builds for CZ, IT and FR languages
