Add concat file downloads in mode hybrid-s3 and s3

[radik121]

When publishing a concatenated file in mode hybrid-s3 and s3, we get an error:

rustus [2025-03-14][11:12:17+00:00][ERROR[] Concatenation is not supported for S3 storage.
rustus [2025-03-14][11:12:17+00:00][DEBUG[] Error in response: Unimplemented("Concatenation is not supported for S3 storage.")
rustus [2025-03-14][11:12:17+00:00][INFO[] "POST /api/tus/upload/ HTTP/1.0" "-" "500" "127.0.0.1" "47.615652"

I would like to solve this problem. Is it possible?
