Changed:
    - ToolType is replaced with ToolAction, which can selectively represent which actions are supported by an item.
    - Added a canPerformAction method to query ToolActions.
    - Renamed canHarvestBlock to isCorrectToolForDrops to match vanilla.
    - Added TierSortingRegistry, which can be used to add custom tiers and supports sorting between vanilla or with other mods.
    
    How to use:
    
    For the breaking system there's 2 methods:
    - getDestroySpeed decides if an item *can* mine the block fast. Override if you have multiple tags or your item isn't a DiggerItem.
    - isCorrectToolForDrops decides if an item will get drops. Returning false will also slow down mining, regardless of getDestroySpeed. Override if you have type-dependant tiers or your item isn't a DiggerItem.
    
    For the tier system mods can just call `TierSortingRegistry.registerTier(tier, "name", List.of(lesser tiers), List.of(better tiers));` to register their tiers.
    There's helper methods to query tiers such as TierSortingRegsitry.isCorrectTierForDrops.
    
    The ToolActions solve 2 problems:
    1. distinguishing which kind of digger an item can be
    2. querying if the item can perform specific secondary actions.
    Any item can override `canPerformAction` to customize which actions it performs.
