Description: Pairwise Hamming distances are computed between the rows
        of a binary (0/1) matrix using highly optimized 'C' code. The
        input is an integer matrix where each row represents a binary
        feature vector and returns a symmetric integer matrix of
        pairwise distances. Internally, rows are bit-packed into 64-bit
        words for fast XOR-based comparisons, with hardware-accelerated
        popcount operations to count differences. 'OpenMP'
        parallelization ensures efficient performance for large
        matrices.
