Hi.

In this PR, set proper color profile values to CGImage (if possible).

This PR and https://github.com/AOMediaCodec/libavif/pull/98 may resolve https://github.com/SDWebImage/SDWebImageAVIFCoder/issues/12 .

Please take a look!

😅 Seems you still trying some changes. If you find it's ready to merge, @ me again.

And, can CI test image been passed after this color space support changes ?

@dreampiggy Sorry! I've done!

And, can CI test image been passed after this color space support changes ?

Unfortunatelly, https://github.com/AOMediaCodec/libavif/pull/98 should also be merged to libavif, and we have to wait the new version release of libavif to fix CI tests.

@dreampiggy Hi! Now libavif v0.6.0 is supported, and all end-to-end tests (Github Actions) have finally passed! Could you take a look?
