Unnecessary point added

[ThatBrianDude]

There is a case where this library adds an unnecessary point when executing a clipperOffset.

In the image you can see a point being generated right in the center of the road. This only happens in a specific positioning of the path.

When I move that waypoint just slightly up it dissapears:

This is the code that Im executing:

    public static List<Vector3> RoadFromPath(List<Vector3> path, float offsetDistance)
    {

        Path64 clipperPath = new Path64();
        List<Vector3> simplifiedPath = SimplifyPath(path, 10f);
        foreach (var point in simplifiedPath)
        {
            clipperPath.Add(new Point64(point.x, point.z));
        }

        ClipperOffset clipperOffset = new ClipperOffset();
        clipperOffset.AddPath(clipperPath, JoinType.Round, EndType.Round);
        Paths64 solution = new Paths64();
        clipperOffset.Execute(offsetDistance, solution);

        List<Vector3> bufferedPath = new List<Vector3>();
        if (solution.Count > 0) // Assume only one path in the solution
        {
            foreach (var point in solution[0])
            {
                bufferedPath.Add(new Vector3((float)point.X, 0, point.Y));
            }
        }

        return bufferedPath;
    }

After further inspection it seems that the unnecessary point is not equal to but VERY close to one of the input path points.

To make this more clear here is a gif of me moving the input point a bit and the buggy point appearing/dissapearing:

Further observation: Switching to Clipper1 completely removes this issue. Il stay at Clipper1 for now until theres a fix for Clipper2.

Thanks for all the effort!
