Return only the data

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi

* gn3/api/heatmaps.py: Parse incoming data to build up correct trait names and
  respond with only the computed heatmap data.
* gn3/heatmaps.py: Return only the computed data for heatmaps and clustering.

  Since GN3 is supposed to handle only the data, and db-access, this commit
  ensures that GN3 responds to the client with only the computed heatmap data,
  and does not try to generate the heatmaps themselves.

  The generation of the heatmaps will be delegated to the UI clients, such as
  GeneNetwork2.
