Description

Loading an image with the following statement:
using var img = await SixLabors.ImageSharp.Image.LoadAsync(new DecoderOptions { MaxFrames = 1 }, fileStream);
should just load one frame, which is does for all images I have tested on, EXCEPT the attached one, where it
imports all 42 frames.

Steps to Reproduce

Load the attached "duck.png" like this:

  using var fileStream = File.OpenRead(@"c:\temp\duck.png");
  using var img = await SixLabors.ImageSharp.Image.LoadAsync(new DecoderOptions { MaxFrames = 1 }, fileStream);
  Assert.AreEqual(1, img.Frames.Count);
