Handling image results with the React Native Barcode Scanner SDK
When returnBarcodeImage is enabled in BarcodeScannerScreenConfiguration.scannerConfiguration, each barcode result includes a cropped image of the scanned frame. This image is represented by an ImageRef, which holds a reference to the image in memory.
An ImageRef can be used to save the cropped barcode image to the file system or retrieve it as a Base64-encoded string. Since it holds native resources, it's important to release the reference once it's no longer needed.
To ensure proper memory management, ImageRef instances should be used within an autorelease block that handles disposal automatically.
