Reads bytes from boundsTree.serialize() back into a tree for geometry,
the geometry it was built from (three-mesh-bvh's MeshBVH.deserialize; the
bytes are our layout, not three-mesh-bvh's format). Either triangle format:
an indexed file gives an indexed tree, which reads its corners from the
geometry's positions. Doesn't set geometry.boundsTree; setBoundsTree does.
