Feature description

When viewing a directory containing JXL files, display previews of those files next to the filenames, as the app does with other image types.

Why do you want this feature?

I have thousands of JXL files on my phone and interact with them frequently via Fossify File Manager. It would be convenient to be able to tell which image is which in File Manager without having to open each one in Fossify Gallery.

Additional information

Fossify Gallery already supports JPEG XL – something I am very grateful for. Since Fossify has decided to support JPEG XL in one of its apps, I hope you will agree that adding support in another app also makes sense to do. File Manager could use the same JXL Glide integration as Gallery.

I do not think the app size bump is worth it, given the current adoption of this format. Fossify Gallery nearly tripled in size due to JXL support (see v1.1.3 vs v1.2.0).
