numpy complex has changed

[rdejtiar]

Running the script with python 3.8 and numpy 1.24.3 I´ve found :
np.complex has to change to complex128
on line 220
self_Z = np.complex128(R_int + Rp+( X_int + X_geo + Xp)*1j)

on line 256
self_Z = np.complex128(Rp+ (X_geo + Xp)*1j)

Thanks for picking this up, should be fixed now!
