doincfish function bug

[xiaoneimeng]

The doincfish function cannot be used properly due to the fact that ML_zeros = np.array(Oo[[idx_zeros]]) constructs ML_zeros as a three-dimensional array. This issue can be resolved by modifying the line to ML_zeros = np.array(Oo[idx_zeros]).
Additionally, after making the modifications and running the example file again, the calculated α95 in the output results differs from the provided results. However, the example's expected output described in the function remains the same. I am currently reviewing the specific calculations.

PmagPy version:
4.2.109
