Bug description

Hi everyone! 👋
I have a lot of photos in my nextcloud and i want to see them all on the map (the ones with gps data ofc).
I placed the .index.maps in every folder and run the command (occ maps:scan-photos) multiple times now.
Still only 10k of my pictures are loaded. (The popup "… remaining" is gone too)
And I know that i have thousands more with gps data from various trips.

Steps to reproduce

1. have multiple folders (and folder in folders)
2. have .index.maps in every (sub)folder
3. have >>10k photos
4. run maps:scan-photos
5. wait

Expected behavior

I would expect them all to be loaded in the map after a reasonable amount of time with a user feedback, like a toast or
best would be a progressbar somewhere.

I expect it to use a fixed and reasonable amount of RAM while processing.

Additional info

No response

Start with the maps:scan-photos command and inspect custom_apps/maps/lib/Helper/ExifGeoData.php at line 114, where the reported memory exhaustion occurs. Reproduce with nested folders and more than 10k geotagged photos, then verify that scanning completes without exhausting memory and processes all eligible photos.
