v2.2.0

This minor release adds a new getSummary() method to the Helper class which supports the IIIF Presentation v3 "summary" element while using the IIIF Presentation v2 "description" element as a fallback. The existing getDescription() method is now deprecated but has been made "summary"-aware.
