Handle rate limit error

[metya]

Hi! Very good repo and work.

But in my test only for one day I've got fail with
{"meta":{"status":429},"error":{"message":"RATE_LIMITED","code":42901}}

I think that possible to handle. I'm not coding in dotnet so I couldn't send PR. But I think it is easy peasy.

Could this be related to #1 ? Did you get many matches before getting this error ?

Not at all. Like maybe 10 or something. Maybe less. It was one-time error. Not noted anymore.
