feature: support writing ICC color profiles

[lovasoa]

Hello and thank you for this great library !

Issue: Currently, the image crate does not support writing ICC color profiles when encoding images. This can result in color inaccuracies or distortions.

Upstream issue:

• Opening and saving an sRGB image yields different colors image-rs/image#2247

Why ICC Profile Support Is Important: ICC (International Color Consortium) profiles define how colors should be interpreted by devices such as monitors, printers, and software. Without embedding an ICC profile in an image, there is no guarantee that the colors in the image will be displayed correctly. Generally images will be interpreted as sRGB by default, instead of the actual color palette of the image.

By supporting the writing of ICC profiles during image encoding, the image crate could ensure that images are displayed as intended across all platforms, and that opening reading an image and writing it back does not distort its colors.

Requested Feature: Add support for embedding ICC profiles when saving images to ensure color fidelity and consistency.

Hi, which formats specifically?

The full specification for ICC color profile encoding is available here: https://www.color.org/specification/ICC.1-2022-05.pdf

But it doesn't need to be implemented in this library. Ideally, zune-jpeg would simply provide something like fn set_icc_profile(&mut self, profile: &[u8]). And users would pass profiles either created by other libraries or (more likely) extracted from the original image with ImageDecoder::icc_profile from image-rs.

Zune-jpeg is a decoder and it does support reading ICC profiles, zune-image will hold an ICC reference in the metadata struct, encoding support is not yet intergrated but can be done in due time.
