Feature Request: Add "timed out" parameter

[R4to0]

Hello!

Been using your library with my Discord bot and works like a charm!

The only issue I'm getting is if I try to rcon a server that is down (or changing map for example), it doesn't report any kind of timed out (at least when using UDP because of how the protocol works) and I have to handle that by myself with a timer or something (haven't tried yet).

Since there's no param for this in the library, it would be nice to have one :)

Here's how I'm using. If the server is up, everything works as expected.

async SendMsgRcon(target, msg) {
 return new Promise((resolve, reject) => {
 // max rcon data we can send is 509
 const maxrcondatasize = 509;
 const basesize = 16 + target.rcon.length; // rcon challenge and rcon length
 const basecomm = `some command here `;
 let conn = new Rcon(target.serverip, target.serverport, target.rcon, { tcp: false });

 conn.on('auth', () => {
 //console.log("Authed!");
 conn.send(basecomm + `"${msg.slice(0, (maxrcondatasize - basesize - basecomm.length - 2))}"`);

 }).on('response', (str) => {
 //console.dir("Got response: " + str);
 conn.disconnect();

 // handle status
 const status = str.replace(/\n|\0/g, "");
 if (status == 'OK')
 resolve(true);
 else /*if(status == 'BADMSG')*/
 resolve(false);
 }).on('end', () => {
 console.log("Rcon socket closed!");
 }).on('error', (error) => {
 console.log("error");
 conn.disconnect();
 reject(null);
 });
 conn.connect();
 });
}```

Thank you for your time.
