Cancels all subscriptions in Amazon Subscribe and Save

	// This script cancels all subscriptions in Amazon Subscribe and Save, which is fairly annoying to do manually one by one (it's def intentional)
	// Inspired by reddit post https://www.reddit.com/r/amazonprime/comments/1d3agri/mass_cancel_move_all_subscribe_save_items_in_bulk

	// Improved on getting subscriptionId, and fetching the urls (so it doesn't open a new tab on every unsub)

	// Ussage
	// 1. Visit this URL showing all subs: https://www.amazon.com/auto-deliveries/subscriptionList?listFilter=active
	// 2. Press the "Show more subscriptions" button until you can see every item you're subscribed to
	// 3. Open developer tool(cmd + opt + i) and paste the following into Javascript console. Then hit Enter
	// 4. Profit
