Subject: [PATCH] Search all APP2 sections for ICC profile data

Apple phones often include several images in one file using the
Multi-Picture Format standard. This is implemented via a MPF0 object
within an APP2 section. Pel should search for the ICC section instead of
returning the first APP2 section.
