Subject: Enable Cross-Origin Resource Sharing

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

* gn3/api/heatmaps.py: Fix bugs in data parsing
* gn3/app.py: enable CORS
* gn3/settings.py: add flask-cors configurations
* guix.scm: Add flask-cors dependency

  For easier testing of the heatmaps generation feature, this commit activates
  the cross-origin resource sharing for all "localhost" origins.
