It is hard coded that the server the default TLS options of http.server are applied. I would like to be able to configure stuff like TLS Versions (since the default ones include deprecated versions), see for example

  srv := &http.Server{
    Addr:    *addr,
    Handler: mux,
    TLSConfig: &tls.Config{
      MinVersion:               tls.VersionTLS13,
      PreferServerCipherSuites: true,
    },

I'd like to keep screego simple, you could use a reverse proxy like nginx to do custom TLS termination.
