* Only requests remote taxon if local is missing or hasn't been synced in a
week
* Returns a localized version of the remote taxon immediately without waiting
to get a newly-created record from realm
* Expands tests to use a unique realm, integrate more of our code, and check
to ensure the API gets called
* Show indicator while loading taxon on ARCamera
* Show iconic taxon found in model results if we can't load a remote taxon
* Show iconic taxon as backdrop for ObsImage whenever possible
