Favicon Middleware

Favicon middleware for Fiber that ignores favicon requests or caches a provided icon in memory to improve performance by skipping disk access. User agents request favicon.ico frequently and indiscriminately, so you may wish to exclude these requests from your logs by using this middleware before your logger middleware.

Note This middleware is exclusively for serving the default, implicit favicon, which is GET /favicon.ico.
