role, style are not rendered in expressAs tag (azure tts)

[aguegu]

const doc = new Document({ language: 'en' });
const body = doc
  .voice('Jenny')
  .expressAs({ role: 'Girl', style: 'cheerful', styledegree: 2 })
  .say('hello')
  .up()
  .up()
  .render({ provider: ServiceProvider.Microsoft });

the expected xml is

<speak version="1.0" xmlns="http://www.w3.org/2001/10/synthesis"
       xmlns:mstts="https://www.w3.org/2001/mstts" xml:lang="en">
    <voice name="Jenny">
        <mstts:express-as style="cheerful" styledegree="2" role="Girl">
          hello
        </mstts:express-as>
    </voice>
</speak>

but the real output is

<speak version="1.0" xmlns="http://www.w3.org/2001/10/synthesis"
       xmlns:mstts="https://www.w3.org/2001/mstts" xml:lang="en">
    <voice name="Jenny">
        <mstts:express-as>
          hello
        </mstts:express-as>
    </voice>
</speak>

the attributes in express-as are missed.

I did not find example about how to use express-as, but the introduction said it is supported. Just not sure how to implement it.

@aguegu 嗨，你好，感谢你的使用 :D，我已经发布了ssml-document@1.0.57，这个版本支持expressAs函数的重载，你提供的示例代码也可以正常工作，此前他的使用方法是必须提供一个内容：expressAs(content: string, options?: IExpressAsOptions, compile?: boolean): Element;，但现在他已经兼容你的用法，retry。
