Filter the list of datasets by feature type (image, audio, class label...)
The idea is to provide the information to moon-landing to improve the search and add tags to help the faceted search.

It might be done by:
-  adding a filter to /valid (/valid?feature_type=image): filters the valid datasets to only include datasets that have a least one split with at least one Image feature type
- or by adding the list of feature types to the /valid route response (or add a new route for that), so that moon-landing could fetch it regularly and update the search index, creating specific tags for every dataset
