fix(client): remove properties from ResponseEsque that are not used

[tjenkinson]

🎯 Changes

Removes all properties from the fetch response type that are not actually used. This is so that the fetch ponyfill also doesn't have to implement unnecessary parts.

Specifically I'm using this library in a Cloudflare worker to make requests to a Cloudflare Durable object worker, and to do that I'm providing the durable object fetch function. This works perfectly 🎉 except it hits a type error though because the Response type in@cloudflare/workers-types (visible here) is

declare class Response extends Body {
  constructor(body?: BodyInit | null, init?: ResponseInit);
  static redirect(url: string, status?: number): Response;
  static json(any: any, maybeInit?: ResponseInit | Response): Response;
  clone(): Response;
  readonly status: number;
  readonly statusText: string;
  readonly headers: Headers;
  readonly ok: boolean;
  readonly redirected: boolean;
  readonly url: string;
  readonly webSocket: WebSocket | null;
  readonly cf?: any;
}

which is missing type which (without this change) is required, but not used.

Here is the error:
