Finish implementing WireAttachmentData.

[JBYoshi]

WireAttachmentData was partially implemented some time back. This should finish it.

Test code: (Drop this into a plugin. source should be a Player.)

        source.getLocation().setBlock(BlockTypes.REDSTONE_WIRE.getDefaultState());
        ImmutableWireAttachmentData blockData = source.getLocation().getBlock().withExtendedProperties(source.getLocation())
                .get(ImmutableWireAttachmentData.class).get();
        source.sendMessage(Text.of("state: ", DataFormats.JSON.write(blockData.toContainer())));

        WireAttachmentData data = Sponge.getDataManager().getManipulatorBuilder(WireAttachmentData.class).get().create();
        data.set(Keys.WIRE_ATTACHMENT_NORTH, WireAttachmentTypes.SIDE);
        data.set(Keys.WIRE_ATTACHMENT_SOUTH, WireAttachmentTypes.UP);
        source.sendMessage(Text.of("individual set: ", DataFormats.JSON.write(data.toContainer())));

        data = Sponge.getDataManager().getManipulatorBuilder(WireAttachmentData.class).get().create();
        Map<Direction, WireAttachmentType> map = new HashMap<>();
        map.put(Direction.NORTH, WireAttachmentTypes.NONE);
        map.put(Direction.SOUTH, WireAttachmentTypes.SIDE);
        map.put(Direction.EAST, WireAttachmentTypes.UP);
        // skip west
        map.put(Direction.SOUTH_SOUTHEAST, WireAttachmentTypes.UP); // fake value
        data.set(Keys.WIRE_ATTACHMENTS, map);
        source.sendMessage(Text.of("bulk set: ", DataFormats.JSON.write(data.toContainer())));

This map can be stored in final static field and referenced here.
