+add "async mode" to `getCloudflareContext`
+
+Add an `async` option to `getCloudflareContext({async})` to run it in "async mode", the difference being that the returned value is a
+promise of the Cloudflare context instead of the context itself
+
+The main of this is that it allows the function to also run during SSG (since the missing context can be created on demand).
