Feature barcode detector parameters #24903 Attempt to solve #24902 without changing the default detector behaviour. Megre with extra: https://github.com/opencv/opencv_extra/pull/1150 **Introduces new parameters and methods to `cv::barcode::BarcodeDetector`**. ### Pull Request Readiness Checklist See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [x] The PR is proposed to the proper branch - [x] There is a reference to the original bug report and related work - [x] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [ ] The feature is well documented and sample code can be built with the project CMake
