Fix "NumbaPerformanceWarning: '@' is faster on contiguous arrays"

[dachengx]

When running pytest -vx ./tests -k TestDeterministicSeed with 0d3fb95, I got a warning like:

tests/test_deterministic_seed.py::TestDeterministicSeed::test_FullChain_DifferentSeed
  /home/xudc/fuse/fuse/plugins/detector_physics/s2_photon_propagation.py:987: NumbaPerformanceWarning: '@' is faster on contiguous arrays, called on (Array(float64, 2, 'A', False, aligned=True), Array(float64, 2, 'A', False, aligned=True))
    result[start_idx[i]: stop_idx[i]] = (matrix[i] @ split_hdiff[i].T).T
