[Feature] Added dib extension for C#

[WhiteBlackGoose]

Now we can do this

Note: I wish I could do the same for F#, but this dotnet/interactive#1808 should be fixed before

should we maybe add this to Plotly.NET.Interactive for now (also making Plotly.NET.Interactive dependent on Plotly.NET.CSharp in the process), to have all in the same place? When this works for F# as well, we can get rid of the Interactive package alltogether and just add the .dib file to the indivisual packages.

It doesn't work if the dib file is written in F#, and it also doesn't work when F#/C# dib file is invoked from F# context. So only C# from C# works for now.

Yes, you can make Interactive dependent on Plotly.NET.CSharp instead of Plotly.NET. Both work. I personally think, that making Plotly.NET.CSharp interactive on its own is a bit better, because a bit more intuitive and less deps for interactive, but yeah, up to you.

When this works for F# as well, we can get rid of the Interactive package alltogether and just add the .dib file to the indivisual packages.

Actually, if we don't care about the size of the package, we could as well just bake everything (C#, F#, bindings) into one package (again, as soon as they fix that bug).
