Ftp.features is undefined when auth is not called

[warpdesign]

When connecting to an FTP using the following code:

const Ftp = new jsftp({
  host: "myhost",
  port: 21, // defaults to 21
  user: "login", // defaults to "anonymous"
  pass: "pass" // defaults to "@anonymous"
});

Ftp.once('connect', () => {
  // features is undefined
  console.log('connected', Ftp.features);
  // can execute commands here
});

Ftp.features is always undefined.
