Subject: [PATCH] Tests/LibGfx: Add a first test for JPEG XL images

This image uses the modular encoding with a very simple prediction tree.
It also makes use of two features: upsampling (x2 factor) and a
non-standard bit depth (10 bits). The file has been generated on
https://jxl-art.surma.technology/ , with the following input:

Width 64
Height 64
Upsample 2
Bitdepth 10

if N > 300
  - NE -6
  - W 6
