Subject: [PATCH] feat: Add availability property to DrivingAnalysisSensor

The `DrivingAnalysisSensor` now includes an `available` property to indicate the sensor's availability. This property returns `True` if the data for driving analysis is available, and `False` otherwise. This change improves the overall functionality of the sensor.
