I wanted to use the library in Unity - but Unity only supports library that target .NET 3.5 or below.
I made some minimal changes to the library to make it also support .NET 3.5
I also changed the target .NET standard 2.0 to target .NET standard 1.0 - by targeting lower .NET standard version, you allow more applications that run lower version .NET framework to use your library, since it works in 1.0, you might as well target 1.0.
