Add cv::linearAssignment() rectangular assignment solver - #29963 Adds `cv::linearAssignment()` to `modules/core`, next to `solveLP`: a Jonker-Volgenant solver that pairs the rows of a cost matrix with its columns at the lowest total cost. It pairs existing tracks with new detections in a tracking pipeline. `costThreshold` is applied during the solve, so a pair that is too expensive is forbidden and a pair is only made when it beats the price of leaving it unmade. Implemented from Crouse 2016, cited in the doxygen. Accuracy and performance tests are included and need no new test data. ### 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. - [x] The feature is well documented and sample code can be built with the project CMake
