[Feature] Battle Emulator / Damage Calculator

[blizzardfinnegan]

Is your feature request related to a problem? Please describe.

I've been playing for a while, and I'm on a really good run, but having trouble with my level 190 fight. Under normal circumstances, at this point I would use a damage calculator as popularly used in harder challenges such as Run&Bun. However, as this game has many unique mechanics, including leveling past level 100 and multiple held items, calculators which use standard pokemon rules don't necessarily apply as well. I've also seen limited instances of moves not existing in other calculators.

Describe the Feature

Something similar to calculators that already exist, with additional implementations specific to Pokerogue such as held items and overleveling.
