Hey reqwest team,
Unfortunately I'm pretty new to rust and it wasn't clear how to get the example

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let resp: HashMap<String, String> =
        reqwest::get("https://httpbin.org/ip").await?.json().await?;
    println!("{:#?}", resp);
    Ok(())
}

to run. It turned out that I didn't just need reqwest = "0.10.0", but instead needed to enable the json feature as well as include tokio = { version = "0.2", features = ["full"] }

I understand why this is difficult to keep in sync with the (rapidly) evolving rust/async story, but
it would certainly be nice to have a copy/pastable example that runs without anything else.

Thanks!
