/*
  Make a function that is exported, this will be the "inject function", which is called when loading the plugin into mineflayer.
  You can load this plugin into mineflayer in three ways:

  1.
  ```
  bot.createBot({
    plugins: [require('./plugin')]
  })
  ```

  2.
  ```
  bot.createBot({
    plugins: {
      afk: require('./plugin')
    }
  })
  ```

  3.
  ```
  const bot = bot.createBot()
  bot.loadPlugin(require('./plugin'))
  ```

    Inside the scope of this function, you should do anything you need to with the bot object, like add properties to it, like `bot.afk`,
    this function will be called when this plugin is called during the login process
