Hi!
Due to NumPy's main namespace being changed in numpy/numpy#24376, here I update NumPy's imports/aliases: e.g. np.NaN and np.infty won't be available anymore. Also, a canonical name for NumPy's float and complex should be used, which are np.float64 and np.complex128.

sctypes will be removed from the top namespace, but its destination is not decided yet - therefore I import it from internal np.core for now.

If it's not good practice to import from np.core, could you just replace this with the float_numpy_dtype fixture?
