Advanced Silage Types

The script globally enhances all bunker silos, biogas plants, and feeding robots by introducing new silage types.

• Integrates GRASS_FERMENTED, CLOVER_FERMENTED, and ALFALFA_FERMENTED fillTypes based on MaizePlus naming conventions for maximum compatibility.
• All new silage types are processed like standard silage, including methane output adjustments for biogas plants.
• Feeding robots now support the new silage types for forage mixing.
• Silos can ferment any supported crop, with unsupported types automatically ignored.
• Forage wagons and harvesters include the new silage types in silage additive systems.
• Users can easily add custom silage types via a structured table.

Thanks to PfalzAgrar and SirJoki80 for the silage textures.
