MultiFormatReader logs NotFoundException while scanning

[motabass]

Describe the bug
I use @zxing/ngx-scanner and see the following console warning on every scan attempt not detecting a qr-code:

chunk-IMDIBY5Y.js:63 MultiFormatReader: non-ReaderException from reader: NotFoundException2
    at FinderPatternFinder2.selectBestPatterns (FinderPatternFinder.js:574:19)
    at FinderPatternFinder2.find (FinderPatternFinder.js:168:32)
    at Detector5.detect (Detector.js:66:27)
    at QRCodeReader2.decode (QRCodeReader.js:63:71)
    at MultiFormatReader2.decodeInternal (MultiFormatReader.js:199:35)
    at MultiFormatReader2.decodeWithState (MultiFormatReader.js:95:21)
    at BrowserMultiFormatReader2.decodeBitmap (BrowserMultiFormatReader.js:41:28)
    at BrowserCodeReader2.decodeFromCanvas (BrowserCodeReader.js:595:21)
    at loop (BrowserCodeReader.js:1120:36)
    at BrowserCodeReader2.scan (BrowserCodeReader.js:1142:9)

I think this warning should not be logged or NotFoundException should really be a ReaderException, i'm not sure. The console.warn was introduced by this commit: f9a638b
