Scroll of cleansing saves 10% of herblore Secondaries

[Felris]

Description:

Scroll of Cleansing was added with dungeoneering 3 years ago, and was never given a use. This use isn't too OP, but makes it do something a little useful at least. Scroll of cleansing saves 10% of secondaries for /mix command. Also added a /data to track how much the scroll has saved.

Changes:

src/mahoji/commands/mix.ts - Add a check for scroll of cleansing, and if found removes 10%(rounded down) of secondaries (using the secondaries filterable). Then updates cleansing_scroll_bank, and appends a short message saying the scroll of cleansing saved ingredients.

prisma/schema.prisma, src/lib/structures/MUserStats.ts - Added cleansing_scroll_bank

src/mahoji/lib/abstracted_commands/statCommand.ts - added /data command to view cleansing_scroll_bank

Other checks:

• I have tested all my changes thoroughly.

Perhaps also just go through the BSO-specific herblore things and see if theres any situations this would be OP or shouldnt apply.

This is probably unsound (prone to overwriting updates due to not awaiting), and you should do it with just 1 call.

Possibly like:

const savedBank = new Bank();
for (const item of items) {
const savings = new Bank();
cost.remove(savings);
savedBank.add(savings);
}
await userStatsBankUpdate(user.id, 'cleansing_scroll_bank', savedBank);

Preferably just put this in the boosts array. We're moving away from the str += because its hard to keep track of formatting them.
