Research direction
Start by reviewing the existing OME-TIFF codec handling and how Bio-Formats opens the JPEG XL-compressed file produced by the tifffile example. Compare the requested level 90 and effort 5 settings with the repository's current codec support, and verify that an OME-TIFF using JPEG XL can be opened successfully in QuPath.

Description
Hi,
Is there any ongoing work to add JPEG XL compression support for the OME-TIFF (ome.tif) format. In my experience, I’ve achieved about a 50% size reduction with this reasonable settings: {“level”: 90, “effort”: 5} compared to jpeg compression. That is quite substantial for WSI sizes. Implementing this could lead to significant storage cost savings.
An image exported with the tifffile library using JPEG XL compression can’t be opened in QuPath (which relies on Bio-Formats):
with tiff.TiffWriter(f'img.ome.tif', bigtiff=True) as tif:
tif.write(img, compression='jpegxl', compressionargs={"level":90, "effort":5})
