System.Text.Encoding.CodePages 8.0.0 instead of 9.0.9 possible

[AlexSefrin]

Is there a way to use System.Text.Encoding.CodePages 8.0.0 in Zugferd.pdf.csharp? Currently, version 9.0.9 is required, but it's not installed with the 8.x framework. Otherwise, we'd have to copy it separately during deployment, which would cause problems elsewhere where version 8.0.0 is used.
Or is there a workaround?

I modified the project file a bit, should be better with the next version
