Request for Event Handling and Improved Auto-Focus Support

First, thank you for maintaining and providing the @capacitor/barcode-scanner library. It has been incredibly helpful for integrating barcode scanning functionality into our applications.

We have encountered some challenges with the library, specifically related to the camera's auto-focus functionality. The camera does not focus properly, so we have difficulties scanning barcodes. While we understand that this might be influenced by device-specific factors, we were wondering if there are plans to improve the library's auto-focus behavior.

If this is not possible, is it possible to trigger events when the camera attempts to focus or fails to focus, or properties to configure or override the camera's focus behavior?
