This makes it so we don't have to try to parse the geometry JSON and
instead can just pass pre-calculated h3 values, which take fewer bytes,
everywhere.
This makes it much easier to troubleshoot information related to a cell
by showing detailed data about a single cell. At this point much is a
placeholder, but we at least get the cell boundary coordinates and a
map.
This also starts to make some code common around doing things like
mapping.
