Support for MongoDB's New Async C Driver

Hi, MongoDB has recently released a preview of their [Async C Driver](https://www.mongodb.com/docs/languages/c/c-driver/current/async-c-driver/), enabling asynchronous, non-blocking operations.

Are there plans to integrate this new asynchronous driver into Drogon to leverage non-blocking MongoDB calls?

This feature would significantly enhance performance for applications handling high RPS, especially where synchronous MongoDB operations currently pose limitations.

Thanks for your great work!
