Assembly signing

[drvic10k]

The assembly available from NuGet is not signed, which is creating a problem when using in a project that is signed

I'm not sure if I want to get into assembly signing for this library, but I'll at least consider it.

If you need a quick fix, I'd recommend just copying the source code directly into your signed project.

I added a preview release of the signed assembly to NuGet with version 1.2.2-preview. If you get a chance to try that version with your project the requires a signed assembly, let me know if you run into any issues with it.

I created pull request #11 with the changes but I won't merge it in right away. If anyone sees any problems with that implementation, feel free to comment on it.
