plugin XEP-0264: fix orientation of thumbnails: Rotation of thumbnailis is now modified according to EXIF orientation data. Original image is not modified as user may want to keep it, and orientation transformation can modify encoding parameters. Update `pillow` minimum version to the first one with `exif_transpose` implementation.
