Box3D from two corner POINT Z geometries. Mirrors PostGIS’s ST_3DMakeBox. The corners are taken verbatim — no swapping or validation of ordering — so inverted bounds are preserved as supplied. POINT inputs without a Z dimension contribute z = 0, matching PostGIS.
IllegalArgumentException if either argument is not a POINT. Returns NULL if either point is NULL or empty.

Parameters
The lower-left corner point (a POINT Z; a 2D point contributes
z = 0).The upper-right corner point (a POINT Z; a 2D point contributes
z = 0).Return type
The 3D bounding box spanning the two corner points.
