Transfer windows-async

[kennykerr]

Hi there, I'm the creator of windows-rs and the windows crate. Now that the windows crate provides future support directly, would it be possible for us to reuse the windows-async crate for something else? I'd like to move more of the async support into a dedicated crate that the windows crate can depend on and windows-async would be an ideal name. I would just need you to send me an owner invite so I can transfer ownership to begin the process. Thanks for your consideration!
