revise Vitessce view config for sn/scRNA-seq datasets

[ngehlenborg]

With Azimuth annotations available, the cell type annotations should be made more visible.

Suggested layout:

The cell sets for the cell type should be listed first in the list, so that they show up in the top left corner.

@ngehlenborg One thing that just occurred to me - lots of clusters are going to get a bit smushed in the violin plot going horizontally.

[ngehlenborg]

Yes, but it would be good to show it. Can we make it scrollable?

[ilan-gold]

I think my point was more that making it smaller than it currently is would be not great. The scrollable idea is good. I'll make an issue for it in Vitessce.

[ngehlenborg]

I think there is not enough space (in the current UI setup) to accommodate a view that is wide enough for all cell types no matter how wide we make it.

We will revisit once hubmapconsortium/portal-ui#2298 has been resolved.
