Stable version of native_drag_n_drop

• Programmers can add the ability to allow certain data types or custom file extensions.
• There is an option to allow other data types as long as one of the dragged items is allowed (thank you @getBoolean).
• Can add a limit of how many items can be dropped at once. There is no limit by default.
• Only has iPadOS 11 and iOS 15 and above support
