Curves must have the same number of control points.

Describe the bug

Using this sample-file leads to an ArgumentOutOfRangeException here https://github.com/ascora/LottieSharp/blob/80d9cf27ccd234d2b23c523f1ad2b0ea2432f07c/LottieSharp/Model/Content/ShapeData.cs#L68

I don't know exactly why the curves don't have the same amount of points, but this json file also works at https://lottiefiles.com/tools/json-editor.

As a fix I changed the line to:

for (var i = Math.Min(Math.Min(shapeData1.Curves.Count, shapeData2.Curves.Count), _curves.Count) - 1; i >= 0; i--)

But I don't really know if this is the correct solution to fix this problem, but at least this prevents the App from crashing and the output looks fine though.
