EncodedRtIp31BottomLevelBvh::PostLoad allocates too much memory

[KonstantinSeurer]

triangle_surface_area_heuristic_.resize((uint32_t)interior_nodes_.size(), 0);

can oom when loading a capture. interior_nodes_.size() is in bytes but only one float per node is needed (1/128 of the allocated amount).

Hi Konstantin,

Thank you for spotting this; good catch! We'll be sure to get this change into a future release.

Tony.
