So you can, for example, call `ky.get(input).json()` directly without having to await the `Response` first. When called like that, an appropriate `Accept` header will be set depending on the body method used. Unlike the `Body` methods of `window.Fetch`, these will throw an `HTTPError` if the response status is not in the range of `200...299`. Also, `.json()` will return `undefined` if body is empty or the response status is `204` instead of throwing a parse error due to an empty body.
