If "data" of API response is empty list, methods return *dict* instead of *list*

[funduck]

For example, if one calls data = market.get_kline(...) and there are no klines found the data will be {code:200000,data:[]} That is at least not expected because of method description

Since a lot of people already use the library it is not possible to change behavior, but may be a good idea to point this case in description

Because the data is empty, more information will be printed https://github.com/Kucoin/kucoin-python-sdk/blob/2f1d9a3851309fb3da92762edcbb900cc40d6381/kucoin/base_request/base_request.py#L111
