Make setting crafting components from KJS more ergonomic.

[tomprince]

What

Javascript objects only support strings as keys, so allow passing objects (i.e maps) with short tier names as keys for defining crafting components.

Outcome

Before (note in particular the need to import Map from java, rather than native JS syntax):

const Map = Java.loadClass("java.util.Map");

GTCEuStartupEvents.craftingComponents(event => {

    //Make LuV+ electrolyzer wires not osmium for funsies :)
    let wireElectricMap = {};
    event.modify(CraftingComponent.WIRE_ELECTRIC, Map.of(
        GTValues.LuV, UnificationEntry(TagPrefix.wireGtSingle, GTMaterials.VanadiumGallium),
        GTValues.ZPM, UnificationEntry(TagPrefix.wireGtSingle, GTMaterials.NaquadahAlloy),
        GTValues.UV, UnificationEntry(TagPrefix.wireGtSingle, GTMaterials.get('sculk_superconductor')),
        GTValues.UHV, UnificationEntry(TagPrefix.wireGtSingle, GTMaterials.get('activated_netherite')),
        GTValues.UEV, UnificationEntry(TagPrefix.wireGtSingle, GTMaterials.Holmium),
        GTValues.UIV, UnificationEntry(TagPrefix.wireGtSingle, GTMaterials.get('monium')),
    ));
})

After:

GTCEuStartupEvents.craftingComponents(event => {

    //Make LuV+ electrolyzer wires not osmium for funsies :)
    event.modify(CraftingComponent.WIRE_ELECTRIC, {
        LuV: UnificationEntry(TagPrefix.wireGtSingle, GTMaterials.VanadiumGallium),
        ZPM: UnificationEntry(TagPrefix.wireGtSingle, GTMaterials.NaquadahAlloy),
        UV: UnificationEntry(TagPrefix.wireGtSingle, GTMaterials.get('sculk_superconductor')),
        UHV: UnificationEntry(TagPrefix.wireGtSingle, GTMaterials.get('activated_netherite')),
        UEV: UnificationEntry(TagPrefix.wireGtSingle, GTMaterials.Holmium),
        UIV: UnificationEntry(TagPrefix.wireGtSingle, GTMaterials.get('monium')),
    });
});

Potential Compatibility Issues

The functions now accept maps with either numbers (as now) or strings (which can be from native javascript objects), so the change should be backwards compatible.

I want to have a look at improving the error handling somewhat, still.

Object2IntMap to avoid boxing?

Also, what does RVN stand for?

Probably reverse voltage names, no?
