Upload of photos is failing due to OpenStreetMap's rate limiting (HTTP 429) #4200

Did you check the latest Lychee version?
Yes, I did
Which PHP version are you using?
PHP 8.4
Detailed description of the problem
Uploading more photos at once (at least 25-30 photos) with size of around 1MB each that are being processed quite fast by server, while GPS data showing on map is enabled in Lychee.org, and map provider set to OSM, start to return upload errors after successful upload of first 20-25 photos.
Problem is caused by OpenStreetMap's implementation of rate limiting, that is returning HTTP code 429 when it's API is being aggresively used (https://wiki.openstreetmap.org/wiki/Error_429).
As a workaround, one can upload photos in smaller batches to avoid rate limiting, but that is not too convenient when uploading bigger amounts of photos, thus some rate limiting on Lychee.org side (or implementing some lazy GPS data loading with slower OSM's server querying) could help avoiding that issue.
Using wikimedia as a map provider may not be an option either due to it's external usage policy: https://wikitech.wikimedia.org/wiki/Maps/External_usage
Steps to reproduce the issue
- Enable GPS/map with OpenStreetMap
- Upload 25+ not too big images with GPS data embedded

Upload to Lychee.org gives following error
