Builds a shaded height-field video (T, Y, X, 3) from a time series of focus sweeps (each frame a z focus stack) (rgbvideo).
The height is the same as in focus_sweep_height_video (maximum focus refined to sub-voxel with a parabola). From the gradient of the height field normals are formed (zscale is the real length of 1 z slice / the real length of a pixel), and Lambert shading towards light (with ambient as an offset) is multiplied onto the colour of height (blue = low → red = high). If the object moves during the sweep, layer consistency breaks and the height jumps (be suspicious only of those times).
