See discussion in #262

Possible ideas:

• Let user choose between core/denylist.py (and an inverted version), which only adds items to via_location.fallback if you've 'added' it to an allowlist. This lets you either:
  • automatically allow and filter photos to deny
  • automatically deny and filter photos to allow

Could likely add some extra stuff to doctor which prints info about denied paths etc.

• integrate with some other photos CLI tool instead? (dont know which, would appreciate suggestions from anyone who uses something)
• pull geolocation data from the photos and add it as fallback location data (or possibly accurate locations? since I think those are exact -- can let user pick either)
