NMC/Gr Lifetime Model is too aggressive with microcycles in battery profile #747

For battery profiles with many tiny rainflow cycles, the qLi2 term in the NMC/Gr model greatly overestimates the degradation.

Fix is to update the model with recent fixes that add a cycle SOC term to the qLi2 calculations which should make the degradation more proportional to DOD.
