Exception "Value cannot be null" in RestApiClient.ParseRateLimitResponse

Hi Jkorf, Thanks for all your work. I noticed a little exception with KuCoin in the RestApiClient.ParseRateLimitResponse method. I suspect that the responseHearder is null in case of error returned.

Here the trace.

Thanks Eric, should be fixed in the latest version of CryptoExchange.Net. You can manually update to this version if this bug is an issue for you
