Feature Request: autolevel (like ImageMagick)

[aviflax]

ImageMagick has a very useful “autolevel” feature that my company has used to good effect. It would be very cool if ImageSharp had such a feature.

Thank you!

I am actually one of the developers for the ImageMagick project and just looked through our code to see how it is done. It should not be very difficult to add this to ImageSharp.

That's great! Thank you!
