m42538/recolour: implement recolouring method of m42141 option 2

This commit eliminates the blending of point attribute values during the attribute transfer process used in geometry quantisation by forcing the blending weight to be 0|1 (m42141). m42538 also recommends to disable the bounded search of the closest attribute from the contributing set by setting searchRange=0. This is reflected by a change to the software defaults and configuration.
