Update NuGet package

[netcorefan1]

This is really an amazing library!
Please update the nuget package to the latest version. The current one contains the "RightOf" issues.
It would be also good to upgrade to the latest .Net core.
Thanks

Appreciate your feedback! I'm however unable to access the nuget account again that was used to publish this package so I'm literally not able to update the package. I could re-release this package as a version 2 but before doing that, I would have to modernize the package a bit. Some changes that I'm thinking of:

• Replace the current PEX unit tests with normal unit tests. (since PEX lacks general support)
• Optimize performance by using Spans

It would be great if someone from the community could help in this endeavor
