Hey

Thanks a lot for the library. It really helped us with our CI setup.

However recently we have started hitting the abuse detection limits imposed by GH https://docs.github.com/en/free-pro-team@latest/rest/guides/best-practices-for-integrators#dealing-with-abuse-rate-limits

When this happens the library seems to just throw an exception. How can I get the Retry-After header? It is part of the exception?
