upgrade mio to 0.8

[biluohc]

Because tokio 1.17 already uses mio 0.8

Looks fine, glad to see that 0.8 has no pain for us :)

Tokio has also recently updated to use mio 0.8, so some of the ecosystem is looking to update to newer 1.x versions. Currently if a project has both notify and tokio in the same workspace, two versions of mio are now pulled in.

With this now merged, would it possible to publish a new pre-release if time permits?

Yeah ping me again if I didn't publish something till sunday.

Released once #390 is reviewed

Thanks a ton!
