[Plugin Request] More interface implementation in GameTwitterPlugin

[slatter666]

I find that the endpoint is different from official X APIv2, so I can't extend more interfaces on GameTwitterPlugin. Could you support more interface implementation in GameTwitterPlugin. Here are some of my requirements:

1. post a tweet with multiple pictures
2. upload media
3. return conversation_id with _search_tweets function
