LibGfx+icc: Verify ICCProfile ID at parse time instead of in icc

Browse source 
Always computing computing the md5 takes some time, but most
icc profiles are small. So that's probably fine.

If this ends up being a perf problem in the future, or if it ends up
rejecting tons of embedded proiles from images, we can row it back.
But let's see if we can get away with this first.
