Improved rarity system

• Rarity chances now depend on how the item is obtained: items that can't be crafted and are hard to find have higher chances of rolling Epic or Legendary
• Netherite is special: it starts from a Diamond roll and gains a random bonus of +0/+1/+2 tiers, reflecting that it's an upgrade rather than a base material

Rarity everywhere

• Items inside chests receive their rarity when you open them
• Mobs have their equipment assigned a rarity at the moment they die
• Villagers and Wandering Traders assign rarity at the moment of purchase
• Items picked up from the ground receive their rarity on pickup
• Works in Creative mode as well

New command

• /legendary scan [radius] — retroactively assigns rarity to all items already present in the world (chests, items on the ground, mob equipment). Useful if you installed the mod on an existing world
