Add QRCodeDetector to JavaScript Build * ADD: js support for qrCodeDetector - cherry picked commit to solve rebase error * CHG. Revert haarcascade path * FIX: Tests without images * ADD: decodeCurved * js(docs): don't require OPENCV_TEST_DATA_PATH Co-authored-by: Alexander Alekhin <alexander.a.alekhin@gmail.com>
