Relax check on google photos takeout

[LunarLanding]

Found that sidecar files from google takeout not always have the 'googlePhotosOrigin' field.
So I disabled the check. Maybe that's good enough?

Thanks. I had a limited Google takeout set to work with. Rather than remove the check entirely I'd rather check several keys to verify at least one is present. Can you take a look at metadata_from_google_takeout() in the same file and check to see if any of title, description, geoData, etc is present? That should be more robust in case an unknown JSON file is found.

All of the keys except for googlePhotosOrigin were present in the problematic json files, so I wrote it so by default it checks for googlePhotosOrigin, and in case that fails, it checks for all the keys that were listed in the docs. This should strictly improve things and fixes the issue I had.
