New Baro Altitude redundancy/fallback handling multiplexed sources.
The new LK baro altitude driver can handle several concurrent baro altitude sources sending at the same time their values.
Some multiplexers like Westerboer, K6mux, etc. will mix two sources (for example a flarm and an LX) and send them to LK.
The new logic is: if a Flarm is connected, we use its baro altitude (if available: it is not granted from a multiplexer).
If no flarm, we use baro altitude from internal/custom sources like Funtrek, Royaltek, embedded drivers and devices.
Then we can select PriorityBaroSources such as devices themselves: LX, LK8EXT1 etc.
And if there is no PriorityBaroSource, we use whatever is available.
If a baro source disappears, we use automatically what is available, within a few seconds.

Although tested, this code must still be checked for multiple concurrent source of data (typically Primary and Secondary Baro Sources).
It is already tested for multiplexers.

Baro altitude redundancy fix, do full reset of channels when no hearthbeats
New Takeoff safety alarm (configuration menu Alarms).
We can now select an altitude over ground at takeoff, above which an alarm will play.
For gliders, this is normally the minimal altitude needed to turn 180 degrees and go back to the airfield in case towing is suddenly aborted.
Depending on airfields and conditions, it can be something between 50m and 100m.
It can be configured in step of 10m or 10feet, up to 500m or 500feet.
When this safe altitude is reached, a soft cabin chime sound is played, followed by a calm voice saying "safety".
Nothing is printed on the screen. This is an aid to pilot to help them concentrate on the towing phase during this early part of the flight, without continously look at the altimeter to know if the safety takeoff altitude is reached.
By default this alarm is disabled, and can be disabled by setting the altitude to 0.
Remember this is a ground altitude (QFE), so if you want to be told when you are 50m above ground, set 50, simply.
The takeoff safety sound will be armed again only after landing, and be automatically in use again for the next takeoff.
Add string function WindAngleToText to be used in LKProcess and in Sideview
New customkey "Toggle Wind Rose"  will change wind direction overlay and infopage from degrees to textual and back.
Example:  245/5 becomes WSW/5
This customkey by default is assigned also inside custom menu.
