Title: Add custom meta hook in WRX import

Wordpress allows plugin writers to add custom meta fields to posts, but the current Pressbooks WRX import does not provide a way to re-import these fields.

This change replaces the specific pb_section_author postmeta update in the WRX import with an extensible postmeta update with a filter hook plugin writers can use to extend the meta fields to update on import.
