.NET Standard 1.3 Port

[clarkis117]

Just a heads up I made a fork of this, to begin work on porting it to .NET Core... the fork is currently building on 1.0.0-RC2 using the netstandard1.5 definitions

I'm also planning on refactoring it, adding unit tests, and possibly Async support too.

I'd love to help.

The fork is now building and running on .NET Core RTM. I also finished integrating async support and added some basic unit tests. One other item to note is that for certain inputs, the library no longer creates and uses temp files. It now works on byte arrays entirely in memory.
