Tokio server/client example?

Question up front: is it possible to use this crate with tokio?

I'm interested in building a library for using the Spotify API; the existing [rspotify](https://github.com/ramsayleung/rspotify) seems to be tied to tokio through its dependence on `reqwest`. I'd like this library to be executor-independent, and looking through [some](https://www.reddit.com/r/rust/comments/etsnh8/futures_and_tokio_and_asyncstd_having_duplicate/fflqhqe) [recent](https://twitter.com/stjepang/status/1241028995250114564) [discussions](http://smallcultfollowing.com/babysteps/blog/2020/03/10/async-interview-7-withoutboats/#extending-the-stdlib-with-some-key-traits) led me to this crate in particular.

I was initially a bit disappointed to see that there was no `client_tokio` example or something similar given that [it's been claimed](https://twitter.com/stjepang/status/1241028992548904960) that `async-h1` doesn't care about the server it's running with. After trying to make such an example myself, I seemed to run into a bigger issue: because tokio's `TcpStream` doesn't implement `futures::io::AsyncRead` (it implements `tokio::io::AsyncRead` instead), I think the orphan rule prevents `async-h1` from working with tokio.

Am I crazy, or is it currently impossible to use this crate with tokio?

EDIT: After further research, it appears like this can be accomplished using a compatibility wrapper, there's an example here: https://github.com/Nemo157/futures-tokio-compat/blob/master/src/lib.rs (which seems to have an additional benefit of not allocating the `Pin`, meaning this should be zero-cost?). I'm planning to keep working on it, if I finish up an example, is that something this project is interested in having added to the examples?

Start by reviewing the crate's existing examples and the linked futures-tokio-compat implementation to understand how Tokio's TcpStream can be used. Done means adding a Tokio client or server example that demonstrates the compatibility approach and confirms that async-h1 works with Tokio.
