Enhancement: Landing Distance

[smitty97]

Hi, wondering if it would be too hard to add landing distance to the display. This would be great for STOL practice.

Looks like you can grab PLANE TOUCHDOWN LATITUDE and PLANE TOUCHDOWN LONGITUDE and then wait for VELOCITY BODY X/Y/Z to zero out. Then get the new PLANE LATITUDE and PLANE LONGITUDE, calculate distance between (https://www.omnicalculator.com/other/latitude-longitude-distance)

As an alternate, Takeoff distance could be calculated as well.. Toggling the parking brake could switch modes from landing to takeoff and get initial Lat/Long, and then another Lat/Long when SIM ON GROUND goes to zero.

Not really a priority for me personally. If you or someone else submitted a pull request, I would consider it.
