When a SvelteKit project is deployed to Cloudflare Pages, the server-side code is supported through Pages Functions (currently in beta). Unfortunately, by using Functions, each request must go through the server-side Functions code even if it doesn't need to. For instance, an immutable asset request to https://kit.svelte.dev/_app/immutable/assets/_layout-ab34ca4f.css would first have to route through Functions.

This is problematic since the request would "count" as a request to Functions even though only a static asset was served. Further, there is a slight amount of added latency.

This change exposes a set of includes and excludes based on static files generated.
