Changes how bale and pallet storage placeables unload their contents.

Instead of spawning all objects at once, an unload request from the storage UI is queued and dispatched in batches every 5 seconds. If the output area is full the mod waits and retries automatically, so you never lose queued items. The pending count is saved to the savegame and survives a reload.

The vanilla unload-amount cap is also removed, so the UI slider goes up to the actual number of objects currently stored rather than the vanilla hard limit.

Compatible with all base-game and modded placeables that use the GIANTS object storage specialization.
