Traits use native async features rather than async_trait

[ActuallyHappening]

I believe the async traits can be updated to use native syntax
There are caveats, but you can manually specify the Send bound on an explicit associated type.

Thanks for the issue @ActuallyHappening! And sorry for only now getting back to you. Feel free to open up a PR with the changes. We also thought about doing this eventually, but we're currently quite busy, so can't make any promises as to when we might get around to it.
