Fixes #4545.
We don't store the level trait for an Oct as an attribute of the Oct itself, so it has to be collected during the initial traversal. This adds it to the
load_octree
command via theLoadOctree
visitor, and then it sets an attribute on the dataset. I looked and this only causes problems for the stream octrees.This fixes an issue wherein loading an octree then results in just the root oct being selected regardless of the selection method.
