No ground up support for 1.12

[WhySoBad]

Versions

• mineflayer: 2.11.0
• server: spigot
• node: #.#.#

Detailed description of a problem

I am testing at a bot on a 1.12.2 server. The bot joins the server and executes a command to get to his home. After arriving at the home point it crashes with the error below. I saw there was an almost similar error at the version 1.8 which is now fixed.

Current code

function join() {
  bot = mineflayer.createBot({
    username: config.USERNAME,
    password: config.PASSWORD,
    host: config.HOST,
    version: config.VERSION,
  });
  console.log(`Connected to ${config.HOST}`);
  setTimeout(() => {
    bot.chat('/home afk');
    console.log('Arrived at home');
    setTimeout(() => {
      start();
    }, 5000);
  }, 5000);
}

RangeError [ERR_OUT_OF_RANGE]: The value of "value" is out of range. It must be >= 0 and <= 65535. Received -1

Expected behavior

The error is caused by prismarine-chunk so I suppose it's caused by a incorrectly loaded chunk.

I get this bug too, but only on a small selection of servers on 1.12.2. Fixed by changing the version to 1.8.
