Whether an ICC profile is present or not, the decoder
should now properly tag the colorspace of pixel data
received by the decoder.

Whether an ICC profile is present or not, the libjxl
encoder wrapper should now properly read colorspace tags
and forward them to libjxl appropriately, rather than just
assume sRGB as before. It will also print warnings when
colorimetric assumptions are made about the input data.
