Automatic sitemap.xml generation now supported 🚀

Find the documentation here: https://github.com/epicweb-dev/epic-stack/blob/main/docs/seo.md

The TL;DR: now your routes will be automatically included in the dynamic /sitemap.xml route! You can handle dynamic segments and exclusions via the handle API on a per-route basis. Check the documentation for more info.

Big thank-you to @lpsinger for contributing the fix and working on @nasa-gcn/remix-seo which is what we're using for this. 🚀
