Refactor for v2

[mdingena]

Changelog (⚠️ breaking changes!)

If you upgrade to v2, you will need to refactor your code:

• Removed PrefabHash export.
• Removed PrefabSlot export.
• Renamed Prefab export to PrefabData.
• Added Prefab export containing combined data from v1 PrefabHash and PrefabSlot.

Update your code:

- import { createString, Prefab, PrefabHash, PrefabSlot } from 'att-string-transcoder';
+ import { createString, Prefab, PrefabData } from 'att-string-transcoder';

- const guard: Prefab = {
+ const guard: PrefabData = {
    prefabObject: {
-     hash: PrefabHash.Large_Guard_Rectangle
+     hash: Prefab.Large_Guard_Rectangle.hash
    },
    childPrefabs: [
      {
-       parentHash: PrefabSlots.Large_Guard_Rectangle.Slot_Large_SwordType,
+       parentHash: Prefab.Large_Guard_Rectangle.slots.Slot_Large_SwordType,
        prefab: blade
      }
    ]
  };

  const string = createString(guard);
