Fixes #2074 (that also caused tiles to be removed and never loaded again when removed from the cache): the issue came from accessing threejs buffer attributes array directly instead of using the recommended getX() method (which is not the same in the case of InterleavedBufferAttribute.
Greatly improves 3D tiles perfs (see screenshots below) by reducing loading time overhead due to internal structures pre-filling (mainly for 3D tiles picking and style) -> part of these structures are now filled on first demand.
