Dear SIPPY team,

I attempted to set a plant order using subspace methods, but it didn't reflect as expected.
The plant orders of identification results are always 2.
The following are the results of running Examples/EX_SS.py after modifying to set the plant order.

sys_id = system_identification(y_tot, U, 'N4SID', 2, SS_threshold=0.1)
print(sys_id.A.shape)
>> (2, 2)

sys_id = system_identification(y_tot, U, 'N4SID', 4, SS_threshold=0.1)
print(sys_id.A.shape)
>> (2, 2)

sys_id = system_identification(y_tot, U, 'PERSIM_K', 6, SS_threshold=0.1)
print(sys_id.A.shape)
>> (2, 2)

I installed sippy_unipi (version 1.0.2) using the pip command.
