GoldSrc servers can't fetch rules and players

[Herover]

My theory is that challenge packets are not parsed correctly.
The following will print some warnings related to getServerInfo done in initialize, but getRules and getPlayers will fail because we keep getting challenge packets.

  const server = new SourceServer('185.236.8.19:27015'); // Some cstrike server
  server.setTimeout(2000);
  try {
    // Set up connection
    await server.initialize();

    const info = await server.getServerInfo();
    console.log(info);

    const rules = await server.getRules();
    console.log(rules);

    const players = await server.getPlayers();
    console.log(players);
  } catch (e) {
    console.error(e);
  } finally {
    // Remember to disconnect
    await server.disconnect();
  }
