统一error类型，确保所有异常都有对应的错误类型

export default class WAError extends Error {

  constructor (type: WAErrorType, message: string) {
    super(`${type} ${message}`)
  }

}

Currently, the gerror module is used with the Wechaty ecosystem, it's very simple and straightforward, read the source code of it is recommended before continuing working on this issue.

GError source code: https:/huan/gerror/blob/main/src/gerror/gerror.ts
README: https:/huan/gerror
