Update all third party dependencies including one with several known vulnerabilities.
Handle Unicode EXIF data which isn't correctly written; at least that's my story. The Gimp saves the colour profile information using sixteen bit Unicode but it appears that one byte is missing from the end of the string and reading it fails. It is now possible to upload these images, but as no colour profile can be found the Fix It button has to be used to install a valid sRGB colour profile. This change makes it possible to upload these images, but they are assumed to be sRGB as their actual profile is not readable.
