Note: The point cloud bounding box is not being updated once the points are deleted. This is a known issue with BKE_pointcloud_nomain_to_pointcloud and Hans is looking into it. Code inspired/built based on the Delete Geometry node. Pull Request: https://projects.blender.org/blender/blender/pulls/134622
