I have a very interesting case: I need to change the folder where the files are actually located, depending on the cookies that the user has. So I really miss the context object in this function as the second argument. Could you add it, please. Example: something like ```js app.use( "/*", serveStatic({ root: "./public/", rewriteRequestPath: (path, ctx) => path.replace('...', getCookie(ctx, 'concrete')) }), ); ```
