.voxel_size doesn't update for downsampled dataset

dataset_1.voxel_size for dataset_1=array(uri, resolution=0) gives the same dimensions as dataset_2.voxel_size, where dataset_2=array(uri, resolution=1), (same dataset where resolution differs) for example

Great catch!

We should also address pulling this for a cvdb volume, which currently errors out (e.g., intern.array(•).voxel_size)
