LNZ parser

[NullPainter2]

Sorry for 2 previously closed pr. This one contains just the LNZ parsing stuff, so the integration can be done more easily.

To load

		linezData.ParseFile("./Resource/linez/catmaster.lnz");
		linezData.ParseFile("./Resource/linez/calico-petz3.lnz");

Reason for that other file? The catmaster.lnz has some default values. Like Whiskers, which some cat's don't have customized.

To handle Ommited ballz

if( linezData.IsBallOmmited( ballID )) 

This feature needs some extra work to add ... I tried different approach, but not adding Ball:Node2D to scene and marking it as ommited feels easier.

To add addbalz:

• addballz ID comes after the ballz. So it is 67 + addbal index

_Ready() {
                ...
		for (var index = 0; index < linezData.AddBallz.Count; index++)
		{
// get parent ball
			var addBallInfo = linezData.AddBallz[index];
			var parentBall = this.ballz[addBallInfo.ParentBallID];
			int addBallId = (int)catBhd.NumBallz + index;

/*
			if (linezData.IsBallOmmited(addBallId))
			{
				continue;
			}
*/
			Ball dummyBall = new Ball(
					texture, palette, (int)addBallInfo.BallSize, addBallInfo.Color, (int)addBallInfo.Fuzz,
					addBallInfo.Outline, addBallInfo.OutlineColor
				);

// position is = parent ball position + addball offset

			dummyBall.Position = parentBall.Position + new Vector2(addBallInfo.Offset.X, addBallInfo.Offset.Y);
			dummyBall.ZIndex = (int)-addBallInfo.Offset.Z;
			this.addBallz.Add(dummyBall);
			AddChild(dummyBall);
		}

_Render() {	

		foreach (var addBall in this.addBallz)
		{
// get the parent ball		
			Lnz.AddBall addBallInfo = GetAddballInfo(addBall.id);
// and its orientation			
			var orien = frame.BallOrientation(addBallInfo.ParentBallID);

// add the offset
			float xf = orien.Position.X + addBallInfo.Offset.X;
			float yf = orien.Position.Y + addBallInfo.Offset.Y;
			float zf = orien.Position.Z + addBallInfo.Offset.Z;
// ... rotate

Whiskerz seem to be just linez ... I didn't figured out how to do their width yet.

		foreach (var whisker in linezData.Whiskers)
		{
			// Either ball or add ball
			
			Ball startBall = GetBallByID( whisker.StartBallID );
			Ball endBall = GetBallByID( whisker.EndBallID );

			// omitted?
			
			if (startBall == null || endBall == null)
			{
				continue;
			}
			
			Line newLine = new Line(null, null, startBall,endBall,whisker.Color,1,-1,-1);

			//add them to the lists
			this.linez.Add(newLine);
			AddChild(newLine);
		}
