Parallelize implementation of HDR MergeMertens. * Parallelize MergeMertens. * Added performance tests for HDR. * Ran clang-format. * Optimizations. * Fix data path for Windows. * Remove compiiation warning on Windows. * Remove clang-format for existing file. * Addressing reviewer comments. * Ensure correct summation order. * Add test for determinism. * Move result pyramid into sync struct. * Reuse sync for first loop as well. * Use OpenCV's threading primitives. * Remove cout.
