[Feature] Traceable stat sources

[fribbels]

Motivation

Currently the user only sees an output number: 243.2% Crit DMG but has no way of knowing which sources contributed to that: base stats, traces, relics, sets, buffs, teammates, lc etc

Goal

Use the new refactored optimizer to add in an option to trace the sources as text, then display them as a tooltip or something

Note

This should wait till after the optimization engine redesign
