Created the State.test_bug_23017_ieee_754_multidim_numpy_arrays system test.
This is to catch bug #23017 (https://gna.org/bugs/?23017), the multidimensional numpy arrays are not
being stored as IEEE 754 arrays in the XML state and results files.
This test checks a rank-2 float64 numpy array stored in the current data pipe against what the IEEE
754 int list should be for it.
