Note: In general, there are multiple solutions and the result which minimizes height is returned, i.e., the (lat, lon) corresponding to the closest point on the ellipsoid. If there are still multiple solutions with different latitudes (applies only if z = 0), then the solution with lat > 0 is returned. If there are still multiple solutions with different longitudes (applies only if x = y = 0), then lon00 is returned. The returned lon is in the range [−180°, 180°] and height is not below −E.a * (1 − E.e2) / sqrt(1 − E.e2 * sin(lat)**2). Like forward above, v1 = Transpose(M) ⋅ v0.
