"""
Goals:
 + Use OKLab
 + Improved clustering logic
 + Parallel, in the same way as anim-ingest
 + Async requests for downloads
 + Include more info about the pokemon (form, display name, icon sprite source)
 + Include megas/gmax/etc, tagged so the UI can filter them
 * Include more images (get more stills from pokemondb + serebii)
 * Include shinies
 * Fallback automatically (try showdown animated, then showdown gen5, then pdb)
 * Filtering system more explicit and easier to work around
 * Output a record of ingest for auditing
 * Automatic retry of a partially failed ingest, using record
