Explore GPU-acceleration for `transform()`

Transforming large images could be optimized by employing GPU acceleration.

I added impact "low" because simply making transformation faster would not significantly improve workflows. To be fair, having a very fast method to transform data on the fly would allow for a cleaner storage workflow where raw, untransformed, and unstitched data can be transformed and stitched on the fly, reducing the need for data duplication. This would be a very impactful task, but it goes beyond just the mere speed-up of the transformation task.
