=head2 sitemap

Return the sitemap index unless the static or a set of dynamic routes is requested.
We have a maximum of 99,990,000 posts we can make under this model
As we have 10,000 * 10,000 posts which are indexable via the sitemap format.
1 top level index slot (10k posts) is taken by our static routes, the rest will be /posts.

Passing ?xml=1 will result in an appropriate sitemap.xml instead.
This is used to generate the static sitemaps as expected by search engines.

Passing compressed=1 will gzip the output.
