Subject: Enable vertical and horizontal heatmaps

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/non-clustered-heatmaps-and-flipping.gmi

* Update the request endpoint, so that it produces a vertical or horizontal
  heatmap depending on the user's request.
