add msr::airlib::EarthUtils::GeodeticToNed method

[zimmy87]

What feature are you suggesting?

Overview:

Right now there is a msr::airlib::EarthUtils::GeodeticToNedFast for converting GeoPoints to NED coordinates, but the algorithm implemented is a approximate that can result in errors of up to 10km. There is a corresponding method for converting the opposite way, msr::airlib::EarthUtils::nedToGeodeticFast, that has a non-fast version, but we don't yet have a non-fast version of msr::airlib::EarthUtils::GeodeticToNedFast.

Nature of Request:

• Addition

Why would this feature be useful?

This would remove any possible error in the WorldSimApi::testLineOfSightBetweenPoints API

There's a file GeodeticConverter.hpp, it was discussed a bit in #3364 (comment) and later as well. I'll try to bring in the changes I made and see if this turns out to be useful, currently it's unused

Ah I forgot about that file, I've updated calls to msr::airlib::EarthUtils::GeodeticToNedFast with calls to msr::airlib::GeodeticConverter::geodetic2Ned in #3810
