Specify the result of decoding (QR, Datamatrix, AZTEC and MaxiCode) as byte[]

Hello, I'm using ZXing.Net.Mobile.Forms, which in turn uses ZXing.Net in a specific Xamarin.Forms mobile project. So I'm absolutely not an expert in the process of barcode decoding. In short, that project scans a barcode that contains some data. However, this data has not 'string' specific format, so we, in fact, want the data as binary. Now we are only using 2 implementations of barcode: Datamatrix and QR. Datamatrix, no problem, we were getting the data by encode the string with ISO-8859-1 and no problem, we could get it. Nevertheless, with QR, that's not the same. When we tried to encode this string with ISO-8859-1 we had lose a lot of information (some characters were mapped to 3f == '?'). So we propose this little alteration, in order to return the text result along with the binary information used to achieve it when applying a specific encoding.
