v1.7.0 - Python 3.12, ICC profiles, EXIF metadata and the usual maintenance churn

This release is officially tested with Python 3.12, adds shorthand optional dependencies for Pillow/Wand (Willow[Pillow]/Willow[Wand]) so as to get the correct image library versions and fixes a few long standing issues

What's Changed
