New script, fit material parameters

[3rav]

From my point of view, a new script would be very useful, which would calculate the values of the parameters of build-in materials and from the MFront library (Chaboche, Yoshida) against the data from the experiment (like LCF; stress-strain; force-displacement).

*PLASTIC,HARDENING=COMBINED
<Re1>, <strain_e1>
<Rm1>, <strain_m1>
*CYCLIC HARDENING
<Re2>, <strain_e2>
<Rm2>, <strain_m2>

Something like OptiMax: https://prepomax.fs.um.si/wp-content/uploads/2022/09/Optimax-USERS-MANUAL-v0.6.4.pdf

Something like in CodeAster:

Maybe Genetic Algorithm (GA from pygad) and https://github.com/cjekel/similarity_measures:

Existing scripts can be used: dat2txt.py and param.py (for .inp)
