Attached is an image with multiple app13 segments, and there is a temporary
patch file to throw exceptions only if parsing is done in strict mode. As
throwing ImageReadException makes other successfully parsed metadata of a jpeg
useless. This temporary patch is only for skipping the multiple app13 blocks (
if encountered ) and not blocking the metadata extraction process further. Real
fix would be to implement proper support of multiple app13 resource data
blocks.
