Full stories support

[itekhi]

Hi! I'm starting a new project, and I would like to use your amazing library!

My project is fully based on telegram stories. So, I noticed there are some missing methods in your API class, for example getAllStories which is listed in td/generate/scheme/telegram_api.tl at the very bottom. Btw, I didn't understand why does your API have deleteStory method, but td has only deleteStories, could you explain please?)

Will you please add these missing methods to the library?

Btw, I'm amazed how well made this library is, the level of integration with Pydantic is just amazing 🤩 Good job!!
