Trying to integrate the proposal from #114 which is orthognal to this proposal but is scheduled for discussion at the upcoming OME-NGFF call, how would this be modified?
Would the input still point at the relative path to the resolution group or should it point at the relative path to the resolution array i.e. `"/0/image"?

A secondary concern is whether this nomenclature is redundant with the
multiscales.datasets.pathmetadata which also defines the path to the array?
