Adding SWIG support for C#

[tranlm]

Hi all,

Great job on this project. I'm trying to update the cmakelist.txt file to create C# bindings using SWIG (appended code pasted below). However, everytime I try to build the project, I get the following error:

C:\GitHub\EasyOCR-cpp\build>cmake --build . --config Release
MSBuild version 17.10.4+10fbfbf2e for .NET Framework

I've tried to update the code to exclude c10::Device from the SWIG Wrapping, but have been unsuccessful. Was wondering if you could add the support for this.

Thanks!
