[Feature Request]: fiori/BarcodeScannerDialog capture video image from centered region only

[slin-sap]

Feature Request Description

Current implementation seems to pass the entire image captured by camera to zxing. This might lead to an unexpected nearby barcode label to be capture instead.

Proposed Solution

It is better to show a focused region like this example screenshot. Or something similar to UI5 sap.ndc.BarcodeScanner animated scanning css effect. This can help user to position camera so that the barcode label fits within the centered region.

In the code, only the centered region needs to be draw to image canvas, and pass to zxing for barcode recognition.

This might require capturing video frame as image as done in sap.ndc.BarcodeScanner and then use codeReader.decodeFromImage API instead of decodeFromVideo.
