Include rate limit in API responses

[njeirath]

We'd like to use the information returned in the rate limit headers to throttle our calls but it doesn't appear that those are returned as part of the API responses.

For the time being we've setup an Axios response interceptor to add the rate limit data to the API responses with something like this:

        this.client.axiosInstance.interceptors.response.use((response) => {
            ;(response.data as any).rateLimit = {
                limit: Number.parseInt(response.headers['x-ratelimit-limit']),
                remaining: Number.parseInt(response.headers['x-ratelimit-remaining']),
                reset: Number.parseInt(response.headers['x-ratelimit-reset']),
            }
            return response
        })

however it would be great if this functionality was included in the library itself.
