geom/m48906: planar mode coding of octree occupancy
This commit introduces planar modes, in the three x,y, and directions, as new representations of the geometry. Planar modes are activated at eligible nodes through a planar mode activation flag coded in the bitstream. Extra syntax is added to the bitstream to indicate the position of the plane associated with activated planar modes. A local eligibility criteria avoids using planar modes in adverse regions of the point cloud and thus avoiding worse compression performance, particularly on dense point clouds.
