support NED 13 elevation queries by using nearest southeast neighbor
Like all Ned13_reader classes, this supports queries off the NED 13 grid. This particular class returns, for non-grid points, the nearest neighbor lying in the (closed) quadrant to the southeast of the query point. This is basically the coarsest form of "interpolation." Elevation estimates are discontinous at grid lines.
