Handle exceeding Github rate limits

From:
https://docs.github.com/en/rest/using-the-rest-api/rate-limits-for-the-rest-api?apiVersion=2022-11-28#exceeding-the-rate-limit

If you exceed your primary rate limit, you will receive a 403 or 429 response, and the x-ratelimit-remaining header will be 0. You should not retry your request until after the time specified by the x-ratelimit-reset header.

If you exceed a secondary rate limit, you will receive a 403 or 429 response and an error message that indicates that you exceeded a secondary rate limit. If the retry-after response header is present, you should not retry your request until after that many seconds has elapsed. If the x-ratelimit-remaining header is 0, you should not retry your request until after the time, in UTC epoch seconds, specified by the x-ratelimit-reset header. Otherwise, wait for at least one minute before retrying. If your request continues to fail due to a secondary rate limit, wait for an exponentially increasing amount of time between retries, and throw an error after a specific number of retries.

Continuing to make requests while you are rate limited may result in the banning of your integration.

It would be nice if simple-github automatically handled this for consumers, though the behaviour should be configurable as there may be cases where consumers would rather schedule other work instead of waiting for the rate limit to grow again.

No files or tests are named in the issue. Start by locating the client’s REST and GraphQL request entry points and existing error handling. Define how configurable retries should use the rate-limit headers and backoff guidance, then add coverage showing that rate-limited requests wait or fail according to configuration.
