[Performance] Improve score simulation performance

[fribbels]

Motivation

Currently some characters have to do this for their combat scoring, which is over 4000 simulation runs on the card load

This comes from having to calculate:

• Optimal substat distribution for body/feet/rope/sphere permutations for 48x substat benchmark
• Optimal substat distribution for sphere/rope permutations for 54x substat benchmark

Goal

Improve the simulation speed / improve the optimal substat algorithm so these characters don't lag the page as much. The goal is to load the sim without a noticeable slowdown.
