Fixed potential read-out-of-bounds issue in ICC profile loading

Fixed potential read-out-of-bounds issue in ICC profile loading

For 8-bit precision color LUT in A2B0 ICC color space profiles
it was skipping every 2nd CLUT value and then reading past the end
of the CLUT data table. Now it properly increments through
8-bit precision color LUT tables in profiles.
