tifffile support in WSIReader #3251
Description
Is your feature request related to a problem? Please describe.
WSIReader currently supports cuCIM and OpenSlide, which can read patches from very large whole slide images without loading the entire image into memory. However, tifffile is another popular library to load TIFF files (which the most common format for whole slide imaging). Although it does not support extraction without loading the whole image, there are use cases that loading the whole slide image is desirable and tifffile can do it faster than cuCIM and OpenSlide.Thus supporting tifffile in WSIReader would be helpful.
