Add simulated values to IV and FI plots for comparison with experimental data

[ilkilic]

This PR enhances IV and FI plots by adding simulated data points at regular intervals for better comparison of experimental and simulated data. These plots are only generated for rheobase type optimisations, and a warning clarifies that they will not be plotted for non-rheobase cases.

Thanks. Will this work for non-rheobase type optimisations?

[ilkilic]

@darshanmandge we do not support non-rheobase type optimisations for those plots. I have added a warning to clarify it

[darshanmandge]

Just to clarify for other users: this PR adds the additional simulated data points for comparing the experimental and simulated IV and FI curves at regular intervals of stimulus amplitudes on the x-axis.
For non-rheobase type optimisations, the curves will still be plotted to compare the experimental and simulated data but only for the amplitudes in the optimisation protocols step amplitudes. Is this correct @ilkilic? You can describe this in the PR description.

[ilkilic]

@darshanmandge Sorry if it was not clear before, but for non-rheobase type optimisations, the plots are not generated at all. I have updated the PR description to clarify this

[darshanmandge]

Ok
