// Execute while having the inventory you want to unstack all items for open.
// Might have to scroll trough the inventory pages before it will work.
// If many stacked items, might have to run it a few times before all are unstacked (not sure why, maybe rate limits, since I have no pauses at all)
// EDIT: Added a pause between API calls :P
