The following code binds the request body to a `Stream`:

Limitations when binding request body to `Stream` or `PipeReader`:
* When reading data, the `Stream` is the same object as `HttpRequest.Body`.
* The request body isn't buffered by default. After the body is read, it's not rewindable. The stream can't be read multiple times.
* The `Stream` and `PipeReader` aren't usable outside of the minimal action handler as the underlying buffers will be disposed or reused.
