Implement better filtering

[vemonet]

Improve repositories and shapes files display and filtering:

• Add faceted search with categories? (biomedical, organization, etc)
• Group shapes files under their respective github repository?
• Enable to sort files by date of last update?

Make it a React component easy to reuse in other apps?

We have a use-case with multiple types of inputs for the different facets (checkboxes for file types, MaterialUI autocomplete for repositories, text box for full text search), and we want the options (e.g. filter displayed repositories based on the search input)

We could not find a good dynamic faceted search, the most relevant options for React are:

• ebi-gene-expression-group/scxa-faceted-search-results: multiple inputs faceted search, but does not seems to support dynamic filtering of displayed options
• eduardobcastro/in-memory-faceted-search

Currently we prefer to implement it ourself (search for "faceted" in the SemanticIndex page). But it could be tricky when we will start to have more categories to filter on.
