Detection fails with corrupted QRCode finder patterns #951

Hi,

I try to decode qr-codes which are part of a sequence. I can decode most of the examples I have, but in some cases zxing-cpp fails because not all qr-codes are decoded.

Below you can find an example.
In the specific case only the first 3 qr-codes are decoded, the last one fails.

Any ideas why it fails?
How can I improve the detection rate for such cases? I use standard ReaderOptions.
Would it help if I pass the single qr-codes to zxing-cpp?

Thanks
Matthias
