Add support for decay prevention via specialized equipment (#9)

[Infinitay]

• Adds support for disabling pouch decay when filling the pouch with Runecrafting cape or a variation of the Max Cape equipped
• Adds support for disabling pouch decay when filling the pouch with an Abyssal Lantern (redwood lantern) equipped when you're inside the GOTR minigame
  • The lantern is active only preventing decay while the player is inside active minigame area (passing the barrier into the minigame)
    • Haven't tested if it only works when a game is active

Closes #9

[Infinitay]

Fixed wrong decay prevention mechanics & logic as of f171942 after new findings https://github.com/Infinitay/essence-pouch-tracking/issues/9#issuecomment-2443339635

• Refactored adding the #shouldPreventFurtherDecay helper method replacing the variable
  • Refactored variables to isCapeDecayPreventionActive, hasRedwoodAbyssalLantern, and isLanternDecayPreventionAvailable
• Fixed not properly preventing decay if player has a cape, or has a lantern in inventory or equipped
  • Using the new refactored helper variables
• Use WidgetLoaded event and GOTR interface instead of varbit to enable lantern prevention
  • Lantern prevention is constant for the session until you leave the GOTR minigame
• Revert changes to VarbitChanged event for clearing pouches if a player leaves the GOTR portal
  • Disable lantern prevention availability if the player leaves GOTR
