Copper actually between stone and iron

Copper is between stone and iron in durability and speed, but no in damage and mining level.

Mining levels should change to be like this:

Wood and Gold can mine: Stone, Amethyst, Quartz.

Stone can mine: Coal, Copper, Iron.

Copper can mine: Gold, Lapis, Redstone.

Iron can mine: Emerald, Diamond.

Diamond can mine: Obsidian, Netherite.

This would actually put copper between stone and iron. Also the damage should:

1. Be the same as iron and decrease by 0,5 the more you use it, maybe being shown with an oxidized tool texture (same with mining speed; start like iron and get worse)

2. Be 0,5 more damage than stone and 0,5 less than iron.
