Stores sitemaps in Cloudflare R2, through its S3-compatible API.

A preset over SiteMaps.Adapters.S3 (same optional dependencies): the endpoint is https://<account_id>.r2.cloudflarestorage.com (or <account_id>.eu.r2.cloudflarestorage.com), the region is "auto", requests use path style and no ACL header is ever sent, because R2 has no object ACLs.

adapter:
  {SiteMaps.Adapters.R2,
   account_id: "0123456789abcdef",
   bucket: "sitemaps",
   prefix: "acme",
   access_key_id: System.fetch_env!("R2_ACCESS_KEY_ID"),
   secret_access_key: System.fetch_env!("R2_SECRET_ACCESS_KEY")}

Files can be served through SiteMaps.Plug or straight from a public bucket or custom domain bound to the bucket.
