[PN] Station Unload Controller

Automated unloading station controller that ensures the module is emptied only when there's enough storage for unloading 4 wagon's worth of items.

Uses the Programmable Network mod found in the COI Discord in the channel: https://discord.com/channels/803508556325584926/1264293900999200858

The controller does the following:

1. Keeps 20 items in the station module to avoid inviting a train.
2. Only fully unloads it if there is storage for 480 items, ensuring 4 wagon trains can be fully unloaded.

WARNING: rotation removes the controller's connections. Each storage and belt will need to be reconnected. It's recommended you check the correct connections without rotation first.

Setup:

• Place down. That's it. Resources can be changed without issue.
• IF rotating, reconnect the 3 STOCK and 2 S modules in the controller to the storages, station module and belts. Click on their names to open them and select the target building.
