Add setMaterialSecondaryARGB (#867)

This is added as a counterpart to setMaterialRGB (which I have renamed to setMaterialARGB to be consistent with other methods). I'm adding setMaterialSecondaryARGB because currently to set material secondary colors in kubejs you need to do:
GTMaterials.Diamond.getMaterialInfo().getColors().setColor([0xff0000, 0xff0000, -1, -1, -1, -1, -1, -1, -1, -1])
Whereas with this change its as easy as the primary color:
GTMaterials.Diamond.setMaterialSecondaryARGB(0xff0000)
