Native BarcodeDetector API performance is bad

[jvhellemond]

☝️ This is more of a tip than an issue:

The performance of the native BarcodeDetector API¹ can be pretty bad², causing animations while scanning to be very choppy. Reducing the maximum number of scans per second helps, a bit. Disabling (or removing) window.BarcodeDetector (before calling .start()) makes QrScanner load the worker script and do its detecting there:

delete window.BarcodeDetector;

¹: Chrome on non-M1/M2 macOS or Chrome OS or Android only, for now
²: In Chrome on my non-M1/M2 Macbook Pro at least, #YMMV
