Allow for Custom Post Status

I’ve registered a custom post status “Archived” as per WP codex guidelines, so it would be great to include my new post status in the post expirator settings.

This way when a post expires, its status can be changed to “Archived”. This feature would be the silver bullet for municipal government websites where the vast majority of posts (news, tenders, employment opportunities, etc.) need to expire while being maintained in the backend for posterity and record keeping.

Thanks for the consideration!
