Hi, I'm new to openCV, and was willing to find and extract barcodes and Qrcodes from an image and send it to ZXwing to decoding. Only started to look at it this week.

OpenCV can detect multiple bardcodes and QRcodes from an image, and provide the points to extract the image, it can even decode the barcode|QrCode itself.

https://docs.opencv.org/4.x/d6/d25/tutorial_barcode_detect_and_decode.html

I tried to get Barcodes first, but the function doesnt seem to be there, or I'm not understanding how to call it.
Tryied then QRCode detection and it's fully there. I used the function and can detect, and read QRCodes perfectly.

Is this feature supported in OpenCVSharp? If not, do you plan to add it? (I've just seen that it's not implemented in OpenCV 4.0.0 but it's there in 4.1.0). So I assume that this must be a new feature... More search, and saw the the feature was introducted in OpenCV 4.5.3

Thanks again for provinding OpenCV to C#, this port is the only one that work for me.
