Projectkk2glider/remaining issues 1311

Consider this changes in relation to issue #1311
Example (from my memory): use Tranis profile, function `d>x`, V1 AirSpeed:
* in companion max V2 was 127
* in opentx simulator V2 could be set much higher

Looks like above code is needed on 9x platform and not on Taranis. Perhaps just RawSource::getRange should provide correct values for different platforms.
