Description
Assuming that a grid system is able to determine the resolution from the input cell ids, we could provide (integer) ids of parent cells via .sel() and a DGGSIndex is able to select all the (children) cells having those parents. It is not possible to pass custom options to .sel() so not possible to manually set the resolution of the input cells.

Research direction
Start by tracing how DGGSIndex handles .sel() and how the grid determines resolution from input cell ids. Determine how parent integer ids could identify all child cells, and how the existing .sel() limitation affects passing a resolution. Done means .sel() accepts parent ids and selects their child cells without requiring custom options.
