Added compatibility with SuperiorSkyblock2

[xSavior-of-God]

Hello, i would like to add the compatibility with SuperiorSkyblock (if possible), becouse i don't like to rewrite every time this plugin only for adding this feature...

There is only one small problem, if the user wishes to use the IslandPrivilege option, he must add this element (https://hastebin.com/igogekiger.bash) inside 'SuperiorSkyblock2/menus/permissions.yml' at the end!

  shopchest:
    display-menu: true
    permission-enabled:
      type: CHEST
      name: '&6ShopChest '
      lore:
      - '&7Access to creation of a shopchest inside the island.'
      - '&7Currently &aENABLED&7.'
    permission-disabled:
      type: CHEST
      name: '&6ShopChest '
      lore:
      - '&7Access to creation of a shopchest inside the island.'
      - '&7Currently &cDISABLED&7.'
    role-permission:
      type: CHEST
      name: '&6ShopChest '
      lore:
      - '&7Access to creation of a shopchest inside the island.'
      - '&7Role: &e{}&7.'
      - ''
      - '{0}'
    has-access:
      sound:
        type: ENTITY_EXPERIENCE_ORB_PICKUP
        volume: 0.2
        pitch: 0.2
    no-access:
      sound:
        type: BLOCK_ANVIL_PLACE
        volume: 0.2
        pitch: 0.2
