Description:
 def set_rollover(self, area, enabled):
 """Configure whether rollover is enabled for streaming or storage streams. Normally a SensorLog is used in ring-buffer mode which means that old readings are automatically overwritten as needed when new data is saved. However, you can configure it into fill-stop mode by using: set_rollover("streaming"|"storage", True|False) By default rollover is set to True for both streaming and storage and can be controlled individually for each one. Args: area (str):
 Either streaming or storage. enabled (bool):
 Whether to enable or disable rollover. """
