WSI (Whole Slide Image) module for reading digital pathology slides.

This module provides a unified interface for reading WSI files across different backends (OpenSlide, cuCIM, TiffFile) with automatic backend selection.

Backend implementations live in the private `_backends` package and should not be imported directly. Use `WSI` to obtain a reader.
