StaticGeometryGenerator: Ensure geometries are updated

[gkjohnson]

Fix #646

Fixes cases where replacing the geometry causes errors on scene update or no change:

• Include the geometry uuid instead of the (non existent) BufferAttribute UUIDs for representing a BufferGeometry hash.
• Discard BakedBufferGeometry instance if it needs to be resized, forcing a full scene geometry update.

cc @ycw @dongho-shin would it be possible to test this to make sure it addresses the problems from #646?

would it be possible to test this

Yes, simply updates the package(in importmap) from NPM registry to this PR:

- "three-gpu-pathtracer": "https://esm.sh/three-gpu-pathtracer@0.0.22?external=three",
+ "three-gpu-pathtracer": "https://esm.sh/gh/gkjohnson/three-gpu-pathtracer@fix-geometry-update?external=three",

Result: https://jsfiddle.net/tq7gxfsb/

Great, thanks for testing! I'll make a new release later this week or so.
