Loads depth confidence data from the data source.
This method must be overridden by subclasses. The base implementation will crash if called.
Called on-demand when confidence data is requested.
- Parameter confidenceFileName: The filename of the confidence data file (e.g., "confidence_00000000.bin")
- Returns: The confidence data as Data, or nil if loading fails or confidence data is not available
- Important: Subclasses must override this method. Do not call the base implementation.
