Find the main entry on the page

Split from #20

Interpreting a page sometimes fails to highlight the main content of the page. Instead the main entry is treated the same as any other content (h-cards, other h-entries on the page)

Describe the solution you’d like

XRay has logic to check the items for one that matches the URL of the page.

A simpler fallback would be to grab the first h-entry on the page but that seems brittle and could be confused if there is an h-feed.
