 An adaptor that chunks up completed futures in a stream and flushes them after a timeout or when the buffer is full.
 It is based on the `Chunks` adaptor of [futures-util](https://github.com/rust-lang-nursery/futures-rs/blob/4613193023dd4071bbd32b666e3b85efede3a725/futures-util/src/stream/chunks.rs), to which we added a timeout.

 The above code iterates over a stream and creates chunks of size 5 with a timeout of 10 seconds.  
-*Note:* This is using the [`futures 0.3`](https://crates.io/crates/futures) crate.
