[FEATURE] Expose underlying HTTP response

[hjoseph96]

Describe the bug I am looking for rate limiting headers in the graphql response -- but I only get back the response body.

These are the headers: https://anilist.gitbook.io/anilist-apiv2-docs/overview/rate-limiting

Am I missing something?

To Reproduce

response = @client.query @page_query, { page: 1, perPage: 100 }

Expected behavior I expect the response to have access to the headers from the request.

Screenshots If applicable, add screenshots to help explain your problem.

We should expose the underlying response. Feel free to contribute!
