Resolves the wind at a geographic point for route timing. Returns the wind
vector to apply, or undefined when no wind data is available (or the wind
is light and variable), in which case the leg is timed as if calm.
The provider takes only a position; bake the sampling altitude into the
closure so this module stays altitude-agnostic.
