在qrCode中输出的长度太长，导致生成的二维码错误，无法扫描登录

create bot

const bot = new Wechaty({
  puppet: new PuppetSimplePad({
    token: config.token
  }),
  name: config.robot_name
})

bot.on('scan', onScan)

// onScan 方法
const onScan = function (qrCode, status) {

这边的QrCode机制和其他Puppet的有所不同,从服务端返回的是原始图片的完整二进制,如果需要在终端输出,需要做一次"转化"

const fileBox = FileBox.fromBase64(qrcode,'qrcode')
const qrCodeValue = await fileBox.toQRCode()
QrcodeTerminal.generate(qrCodeValue, { small: true })

详细可以参考demo/bot.ts
