convertTrajectory bug with LMP and unitXY ft
cc @gehrmann @debasisc @joshtownsend phil.summerfield
For method LMP, with TN azimuth, with trajectory CRS BOundGeog2d, then if the unitXY is set to "ft" there is an incorrect scaling. See example below. The input is at 4E, 45N, the output point is moved. We tested that for method "AzimuthalEquidistant" the output is correct and not moved. So the issue is why is it applying this incorrect scaling/moving for LMP.
