Add KingGoldemar Sim

[nwjgit]

Description:

• Fix King Goldemar sim not showing dwwh in loot image.

Changes:

• Add custom logic for /kill name: King Goldemar
• Update calcDwwhChance to be usable inside simulatedKillables so that variables only ever need updated once.
• Move simulatedKillable before osjsMonster inside kill.worker.ts to always prioritize custom logic first.
• Update the autofill logic for /kill to prevent monsters like King Goldemar from showing twice.
• Add a message field to SimulatedKillable interface. *See example image below

Other checks:

• I didn't notice the simulate() at the bottom of Boss.ts until after making this PR. I'm not really sure where this is used at besides the unit test. Let me know if changing calcDwwhChance() is a no go, or if you want it done another way.
• I have tested all my changes thoroughly.

The calcDwwhChance function signature has changed, but this call still uses the old signature. Update the call to use the new parameters: calcDwwhChance(bossUsers.length, bossUsers.some(i => i.user.gear.melee.hasEquipped('Ring of luck'))).

This should be roll(quantity) outside the loop, its a lot more efficient/faster as it doesnt need to create an object for every single iteration. If you must do it in a loop (not in this case here), the other way is: .roll(1, {targetBank: loot})

It doesn't necessarily need to be inside the loop, I was just going off how the others are structured. Let me know if this change looks good and or you want me change the others aswell.
