Do not call the base implementation.
override loadDepthData	Data?	Loads depth data from the data source. This method must be overridden by subclasses. The base implementation will crash if called. Called on-demand when depth data is requested. - Parameter depthFileName: The filename of the depth data file (e.g., "depth_00000000.bin") - Returns: The depth data as Data, or nil if loading fails or depth data is not available - Important: Subclasses must override this method. Do not call the base implementation.
