ExtraHoloPage

Default compat with AoF and SoF has been added.
Allow you to use code to add items to the HoloSphere on a new page called "ADDON" (similar to "CRFT").

Ensure that your Item implements the IModularItem interface; otherwise, it may cause a crash.

public static void onClientSetup(FMLClientSetupEvent event) {
    ExtraHoloRegister.register(Item item);
    ExtraHoloRegister.register(Item item)
        .setTexture(ResourceLocation texture, int w, int h, int u, int v);
}
