ESM support will be required after Wechaty v0.69+

[huan]

Currently, the Wechaty ecosystem is moving from CommonJS to ES Modules.

The Wechaty will be Dual-ESM-CJS-Module supported, and the default mode will be under ESM.

• Support ESM module (Dual-ESM-CJS-module) Chatie/tsconfig#16

In order to load Wechaty Puppet under ESM mode by setting the environment variable WECHATY_PUPPT, or by setting the options.puppet = 'wechaty-puppet-xxx', the puppet provider NPM module must support ESM.

If the puppet does not support ESM, then the Wechaty will run into the below issue: TypeError: MyPuppet is not a constructor

• TypeError: MyPuppet is not a constructor getting-started#203

We have added a workaround in Wechaty so that it can load CJS puppet modules.
