Curve fitting for ReRAM drift noise

[HeatPhoenix]

So I've been thinking about how to best curve fit the drift noise polynomials in: src/aihwkit/inference/noise/reram.py

I am aware the data is only taken from 4 points, but I figured it'd make for nicer experiments and graphs to take also the intermediate values in some way.

Any ideas on how to best tackle this?
