Add Headers response (#193)
* Add `Headers`

Example usage:

```rust
use axum::{
    route,
    routing::RoutingDsl,
    response::{IntoResponse, Headers},
    handler::get,
};
use http::header::{HeaderName, HeaderValue};

// It works with any `IntoIterator<Item = (Key, Value)>` where `Key` can be
// turned into a `HeaderName` and `Value` can be turned into a `HeaderValue`
//
// Such as `Vec<(HeaderName, HeaderValue)>`
async fn just_headers() -> impl IntoResponse {
    Headers(vec![
        (HeaderName::from_static("X-Foo"), HeaderValue::from_static("foo")),
    ])
}

// Or `[(&str, &str)]`
async fn from_strings() -> impl IntoResponse {
    Headers([("X-Foo", "foo")])
}
```

Fixes https://github.com/tokio-rs/axum/issues/187

* Make work on Rust versions without `IntoIterator` for arrays

* format

* changelog
