Handle set-cookie for redirects

[maccyber]

Seems like we need to handle cookies that are set when the response is 301, 302, 303, 307, 308.

e.g. 302 responses can contain response.headers.set-cookie that we need to store.

To implement it fetch needs to handle redirects manually:

...
const response = await fetch(input, {
  ...interceptedInit,
  redirect: "manual",
});
...

... and check if it is a redirect status in response.status, then if it's a redirect; recursively call it self with something like.

...
    const redirectStatus = new Set([301, 302, 303, 307, 308]);
    if (!redirectStatus.has(response.status)) return response

    const redirectUrl = response.headers.get("location");
    if (!redirectUrl) return response;

    return await wrappedFetch(redirectUrl, init);
...

We also need to add a maxRedirect option to check against a counter to avoid redirect loops.

I don't have the time to finish this now, but started a draft that i think will work. Maybe someone will pick it up :-)
