Added the Batch Mechanical Crafter, allowing each slot to hold a full stack of items and craft them simultaneously. Added the Batch Repackager, which processes batch crafting packages into a format compatible with the Batch Mechanical Crafter. It correctly accepts and outputs multiple packages when raw material quantities exceed a single package's capacity, and processes packages containing multiple recipes in order, ensuring the materials within a single package are always multiples of the amount needed for a single craft. Added a toggle for Demand Request Mode in the Factory Panel's recipe configuration (only visible when connected). This mode treats the configured recipe as the minimum value for a single craft and attempts to request all required ingredients at once to fill product shortages, sending the maximum available batch size when network supply is limited. Fixed a server-side issue caused by mixing client-only classes.
