Async support

[DaneSlattery]

I'm not sure how to do this, but asynchronous support seems like a very popular feature in embedded rust.

Any updates on this?

It should be a matter of implementing an Async mod with async variant of the driver, could be using embedded_hal_async instead of embedded_hal

No updates as of yet, but my understanding of async is a bit deeper now at least

I've done async for another library, I recommend using maybe-async or bisync crates. It simplifies things quite a lot.
