Implement scene based coverage access
[OGC API Coverages](https://docs.ogc.org/DRAFTS/19-087.html#rc_scenes) provisions a scene based coverage access, i.e to open individual scenes within a collection.
With minor adjustments, we should get this functionality "for free". We could, however, report the scenes CRS/bounds instead of the collections.
