Add auto_dalle plugin

[Jipok]

I had to do a couple of quick hacks to make this functionality possible. I removed the helper forwarding and now forward the telegram bot, update, and chat_id to the plugins. Thanks to this, I rewrote auto_tts and now call the existing code, which takes into account the money spent and shows the work indicator in the telegram.

Need testing.

The direct_result mechanics are somewhat annoying. It’s bad that the chatbot doesn’t see what prompt it used for dalle. And the chat bot cannot perform several actions at the same time: for example, send a picture and a voice message, or a text message. Or several pictures/voice messages.
UPD: Well, it seems that switching to a new version of calling functions can solve this problem: https://platform.openai.com/docs/guides/function-calling/parallel-function-calling
