This script allows you to replace the default WorkshopParentScript.VendorTypes containers with a custom vendor chest.
On an NPC furniture object that has a VendorWorkshopObjectScript, set it to use this script instead. Create your custom VendorChest and add it to a hidden Cell. Then link it to this scripts CustomVendorChest property ObjectReference.
When the NPC Vendor opens shop -- they will no longer sell their default items, they will sell the items from your CustomVendorChest.
