Add-ons [021] ChatGPT Framework 2.1.1

Huge Refactoring!

• Codebase update to improve the developer experience with the ChatGPT API
• Vision support in the message repository
• New DTOs to simplify API work with OOP

Big Note
This version is not compatible with add-ons running on ChatGPTFramework 1.0

• Support for function calling

Fixed​

• When streaming the bot's response, characters such as "0" could be missed.
• Thanks @Rena
