LibGfx+icc: Look at profile_size field

Browse source 
This trims the input bytes to the profile size stored in the file.
Alternatively, we could reject files where the stored size doesn't
match the handed in size. But ICC profiles can be embedded in other
files, and those could conceivably pad the ICC profile data some.
