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.
