Add a pity system

[AceSurvival]

Describe the feature

A pity system for crates, a configurable amount per crate.

PitySystem: Enabled/Disabled
PityAmount: (Example: 10)
PityChance: (Example: 20)
PityMessage: "This roll you receive a pity roll! You are guaranteed a good item on this roll."

Basically when this is enabled, you can guarantee a good item. So given my example configuration, you open 10 keys then the pity system kicks in. When you open your 11th key, you get the pity roll. When the pity roll runs, you get GUARANTEED any item with a chance equal to or less than the amount configured.

So if in a crate you have
Diamond: 60 Percent chance
Emerald 70
Netherite: 20
Ancient_debris: 15
diamond_sword: 10

on your 11th roll, you'll roll for a chance at netherite, ancient debris or diamond sword only. Then, it resets the count to 0 til your next pity roll.

I would sugest a better approach to this have more traditional "gacha" system have let's say predefined 5 rarities and each rarity will have own settings
pity - max pity for a garantee
50/50 - have a 50/50 chance to win "limited item" or "standard item"
chance for 50/50 - be able to modify 50/50 chance to be for example 75/25 win/lose
base chance - normal chance to get item with that rarity
soft pity - have your chance increase by set amount after reaching x amount of open keys
soft pity formula - how soft pity would be calculated
max soft pity limit - maximum chance to have when in soft pity range
static soft pity formula - example rare item will have base chance of 5% and pity of 10 and soft pity of 9 that will be 50% no matter what

for "limited" and "standard" items there would be 2 lists of items needed if 50/50 is enabled if not only 1 list of items would be needed each rarity pity is tracked independently

more modes for rolling with "gacha" system override mode when player would select a single item from "standard" or "limited"
items as a wanted item there would be 50/50 to lose to any "standard" or "limited" item in the list expect the one that player wants

fate point example player would need 2 lost items to garantee wanted item there would be 2 limited featured items and standard items base chance between limited and standard would be 75/25 and then between limited 50/50 if player lost to standard then next will be limited fate point resets when player gets wanted item

I've been tinkering with this idea for a while and wrote a prototype of this gacha system for my self and I see it as interesting idea for crates to have a hard pity garantee for legendary items and well every rarity item
