As discussed in https://github.com/cloudflare/odoh-server-go/pull/16, it might be a good idea to check if the key and cert files passed in as environment variables exist before calling http.ListenAndServeTLS.
This may not be necessary if http.ListenAndServeTLS fails with an appropriate error when the files do not exist.
