Describe the bug
Fitting seems to be inadequate for a p(R1,C1) circuit with large values of R (eg 1e+9) e small values of C (eg 1e-12)
To Reproduce
Steps to reproduce the behavior:
I have a synthetic data for a p(R,C) circuit in the frequency range of 10^5 Hz to 1 Hz
impedance.py does not fit it. It seems to hold constant one of the parameters.
Expected behavior
Since it is a synthetic data, fit should be perfect.
Additional context
I have been using this excellent package for a couple of days, and found this difficulty trying to fit data obtained from a painted metallic surface on NaCl 3.5% (it is a corrosion study), with these high values of R and small values of C.
Congratulations for this excellent software.

I also had a problem with fitting impedance data when the parameters were supposed to be very small $<10^{-10}$. This was related to a bug in scipy.optimize at the time: scipy/scipy#18793 (comment)
Could this be related to your problem, @flamariond? Which scipy version do you use?
