/// This component is responsible of the Inventory which listens for purchases from the StoreManager, and increments the inventory count 
/// for items being tracked in the inventory
///
/// It keeps the inventory stored in PlayerPrefs.
/// Besides keeping count, it also helps in keeping track of items to be equipped in the next game using ToggleEquip.
/// Once the equipped items need to be consumed (i.e. item count needs to be decremented), ConsumeEquipped needs to be called.
/// Other query methods for UI purposes are available (HasEquipped and GetPowerupCount)
///
/// Note that each purchase counts as 5 items of the bought product, e.g. LifePack is 5 hearts. This might change in the future and might need to updated accordingly
