ICC profile read/write support

[Shnatsel]

ICC profiles are important for color management, and being able to read them is crucial to be able to display them correctly, while being able to them is crucial to be able to roundtrip images without visual loss for most formats.

Among other things, this is needed by wondermagick.

I split the checkbox for webp crate support of ICC profiles into a new section, because I kept seeing a "WebP" checkbox unchecked and clicking it (because WebPEncoder::set_icc_profile is available).
