Pull request overview

This PR addresses failures when opening NGFF/Zarr WSIs from URL-like paths on Windows by improving URL/path handling and ensuring Zarr open calls receive needed storage options (notably for S3-backed reads).

Changes:

• Switches WSIReader path normalization to UPath to avoid Windows pathlib mangling of s3://... paths.
• Updates NGFF detection to forward reader kwargs into zarr.open(...) (to support storage_options for cloud stores).
• Updates the S3 NGFF test endpoint URL and adds an s3fs runtime dependency.
