This reads the photoshop image resource.
Currently it only compares the iptc/iim hash with the stored hash, which is used to determine the precedence of the iptc data. In future it may extract some other info, like url of copyright license.
This should generally be called by BitmapMetadataHandler::doApp13()
string | $app13 | Photoshop psir app13 block from jpg. |

we can almost use getimagesize to do this but gis doesn't support having multiple app1 segments and those can't extract xmp on files containing both exif and xmp data
string | $filename | Name of jpeg file |
