support Typescript

[shixin-guo]

@madawei2699 I'm developing an open-source Chatbot called my-bot using Zoom Chat. To speed up development and attract more contributors, I'm deploying it on Vercel. I plan to incorporate the MyGPTReader features into my bot, but I noticed that TypeScript support is on your to-do list. Would you be interested in collaborating? I can do it will be based on your code (new branch )and support Zoom Chat together to MyGPTReader and rewrite it to TS. Once I've completed it and you've reviewed it, we can merge it to your repo and work on it together.
once you confirmed to choose TS, I will start to do it! how do you think
