* fix up implementation of notSelectable in value set filters
* Add check for multiple version matches for a versionless canonical reference
## Other code changes
* Fix narrative generator generating duplicate anchors (prefix 'hc')
* exclude .DS_Store from generated zip files
* Add cross-version support extension
* Add ConceptMap utilities in support of cross-version module
