[Feature Request] Implement BAI Chat API Key support.

[programminglynx]

Suggestion/Bug Fix

Proposal : Implement a system to allow BAI Chat to be connected to via an API Key.

Explanation : This would fix the current issues with BAI Chat and open the way to changing the BAI Chat model in the future.
I am currently unable to find the name of the BAI-Chat free model (and I am unsure if it even exists) in the BAI Chat documentation (https://docs.theb.ai/quickstart) but believe that adding API functionality will be beneficial in the future, particularly if we also were to implement the ability to choose the model.

(I will be trying to learn how to implement this myself but it will be a long time before I can manage such a thing. Thank you for making such an amazing project!)

We have added a new modular way to add new peoviders and models, though I haven't documented it yet. I will try to document it soon so that it will be quite easy for you or anyone else to implement it

You can now use OpeanAI handler with "https://api.theb.ai/v1/" as endpoint and your api key
