Pass through Reader response body type to Deno's HTTP server

Deno’s current Response interface allows Reader as the body type.

/**
 * Interface of HTTP server response.
 * If body is a Reader, response would be chunked.
 * If body is a string, it would be UTF-8 encoded by default.
 */
export interface Response {
  status?: number;
  headers?: Headers;
  body?: Uint8Array | Reader | string;
}

This would be convenient to have in oak since, for example, dejs renders its templates to a Reader.

@dbohdan I think you need to do a --reload. Using your example works for me.

$ curl localhost:3000/reader
Hello, Reader!%

(To prevent this sort of confusion maybe you could aggressively version oak like Deno’s std is versioned? I am not actually sure it would be worth it.)

I am/do. I just wanted to try to get as many bug fixes into before cutting a version.
