Requested enahancement or feature

• Update the games() function introduced in Add initial version of games catalog #753 so that it takes arguments on which to filter the results using both game attributes and metadata.
• Some ideas were explored for this in Add Catalog of games #735
  • Could still use the catalog.yml to get the metadata for a dataclass; the catalog could be refactored into a list of dataclass instances, where they either include a callable function or the file
• Pre-requisite: [Catalog] Autogenerate game families #758
