portable.accord.* nugets version: 3.1.0-pre shim 2.1.0-pre shim.drawing 3.0.1

iOS version 9.3.3

I think the reason of a problem is shim version. I moved back to portable.accord 3.0.2 and shim 2.0.1 and it works now.

@AndrewKaplanovsky Thanks for identifying this problem. I will have a look at it as soon as possible.
