Feature request: Use persons/pets as an include/exclude filter

[rohitsud]

Google Photos optionally allows facial recognition and grouping for people and pets in the photo. It would be nice to have a filter for that since that is a useful feature to automatically categorize pictures into albums.

For now, it is possible to do it indirectly:

1. Use pet/person name as a search query, it should bring up the same media that are in the auto-generated album.
   May not be 100% identical, I have not tested it extensively, but I have not noticed any differences in my library.
2. Using GPTK add search results to an album.
3. Use this album in filters.
