#76 Add CompostableUtils feature

This update introduces the CompostableUtils class into the growthcraft.core.utils package. The class includes methods for registering an item as compostable with specific or custom compostability values, and retrieving the compostable value associated with a given key. This helps facilitate compostable items management in the Growthcraft mod for Minecraft.
