[plugin-barcode-scanner] QR-Code Format can't be disabled on android

[Mewlkor]

Describe the bug

The android code always adds the QR-Code format to the list of supported formats for scanning.

plugins-workspace/plugins/barcode-scanner/android/src/main/java/BarcodeScannerPlugin.kt

Line 258 in ea033fe

.setBarcodeFormats(Barcode.FORMAT_QR_CODE, *mappedFormats).build()

I am not sure if this also happens on iOS but as far as i can tell it only affects android.

Reproduction

1. Create minimal Tauri app for android
2. Add barcode scanner plugin
3. set format list to exclude QR code
4. Scan QR code

Expected behavior

A format list without QR-Code should not scan any QR-Codes.

Stack trace

Additional context

I linked the offending line. This is only an issue since i have some cases where barcodes and QR-Codes appear in the same frame and i only want barcodes.
