Asynchronous IO Support

Hi,

We are currently reviewing if we should use this Python SDK or go for bare HTTP calls (in a Python enviroment).
While the SDK has many advantages the major disadvantage we see is that all methods seem to be synchronous.
Given that this is just a wrapper around the HTTP API calls using `requests` this will cause blocking invocations because of the IO nature of HTTP which isn't great for performance.
Are there any plans to implement `async` methods or create an `async` version of this SDK?
