DJI OSD - Display Air Speed via dji_use_name_for_messages re-purposing

[Jetrell]

Currently @digitalentity has implemented a re-purposing of the dji_use_name_for_messages. So that other warnings and data can be displayed on the OSD. #6287
This gives even more flexibility to the OSD in the DJI goggles.
The current layout is -

// :W T S E D
//  | | | | Distance Trip
//  | | | Efficiency mA/KM
//  | | S 3dSpeed
//  | Throttle
//  Warnings

I would like to request that a CLI command be added for the 'S' data. So that Speed can display as either 3DSpeed or Air Speed.
This would be great for those of us that have air speed sensors hardware left over on our planes, from use with the analog OSD.

Thanks

I dont have an airspeed sensor but will look into this. Just got a contact who could test it properly
