Support for "poe" API Integration

[lam0819]

Hi team,

First, thank you for the great work on this library!

I'd like to request support for integrating the "poe" API, specifically its "thinking model" in JSON format. This feature would be valuable for users who want to interact with or build on top of the "poe" model programmatically.

I don't plan on supporting Poe as a first party provider
