feat(barcode-scanning): add cornerPoints option

[robingenz]

Plugin(s)

• Barcode Scanning
• Face Detection
• Face Mesh Detection
• Selfie Segmentation
• Translation

Current problem

Currently, all detected barcodes are passed to the webview, even if they are outside a scan area. This leads to unnecessary data being transferred between the native layer and the web layer. In addition, some logic needs to be implemented at the web layer to filter out the barcodes that are outside the scan area.

Preferred solution

Add a cornerPoints option that allows you to define a valid area on the native layer. In the first step, this should have no effect on the size of the camera view. This information should only be used to filter the barcodes on the native layer.

In the next step, something like #79 could be implemented.
