Cannot unmarshal number into Go struct field CancelOrderByIdResponse.order-state of type string

[gregzaitsev]

Huobi response contains numeric order state in case of cancellation error, so this deserialization results in marshalling error:

result := order.CancelOrderByIdResponse{}
jsonErr := json.Unmarshal([]byte(postResp), &result)
