Support decode QR code from Curved surface and window.PollKey()

[lcmmhcc]

im trying to use a wide-angle camera but can't decode the qr code from the image. it can detect the qr img, but fail to decode it. ive tried many times. i suppose may be it can decode by calling the method below

cv::String | decodeCurved (InputArray img, InputArray points, OutputArray straight_qrcode=noArray()) (https://docs.opencv.org/4.x/dc/d84/group__core__basic.html#gad9287b23bba2fed753b36ef561ae7346)())

Description

another question is window.PollKey() is not supported and each time window.WaitKey(1) is called may cause a little delay by showing the image in window.
