Upgrade to Wechaty v1.x API

[huan]

The current version of SimplePad can be only used with the Wechaty v0.x because the v1.x has changed lots of export names (and some variable names)

It would be great for the Wechaty v1.x user to continue to use SimplePad by upgrading the codebase to support the Wechty v1.x.

I'd like to contribute if we can start planning the upgrading.

The above PR has also enabled the ES Module feature, which is highly recommended.
