For function such as futures_historical_klines, default limit should be "None"

[wanga10000]

When users do not specify the limit parameter, the function currently returns only the default 500 rows of klines. To retrieve the full range of klines between start_str and to end_str or the latest time, users are required to explicitly set limit=None. This behavior is counterintuitive, as the expected default when limit is not provided would be to return the complete dataset within the specified time range.

I’ve opened a PR #1607 to address this issue. The change updates the default limit for the futures kline helpers from 500 to None, so they now fetch the full requested range by default. This makes the behavior consistent with the spot helper and removes the need to explicitly pass limit=None.

Closing as solved in #1607
