[async-std-resolver] Re-export AsyncStdConnection(Provider)

[romanb]

Analogous to the definition of TokioAsyncResolver with re-exported TokioConnection and TokioConnectionProvider, it would be useful to have AsyncStdConnection and AsyncStdConnectionProvider re-exported in the public API of async-std-resolver, so that types like this

struct Foo<C, P> {
   // ...
   resolver: AsyncResolver<C, P>
}

can be instantiated via

type AsyncStdFoo = Foo<AsyncStdConnection, AsyncStdConnectionProvider>;

[djc]

Seems reasonable!

Thanks for the PR!

@djc and @bluejekyll would it be possible to release a new version of async-std-resolver which includes this patch? We would like to use async-std-resolver in specific and trust-dns in general in rust-libp2p, see libp2p/rust-libp2p#1927 and libp2p/rust-libp2p#1931 both of which depend on this small change.

[bluejekyll]

Yes, it's definitely possible. Let me see about a couple of PRs that might land soon before we do the next release.

Thanks @bluejekyll for the new release!
