Publishing the .NET Standard version to NuGet

[CameronAavik]

Hi, I have a library I am writing at the moment where I would like to be able to use QuotationCompiler but the only published version on NuGet is the .NET Framework version. I noticed that in the code now that the library is .NET Standard, would it be possible to publish that version or is not ready to use yet?

Also, I noticed that you have been making a lot of contributions now to FSharp.Quotations.Evaluator. Does that library include all the performance improvements you made here? Or is QuotationCompiler still faster?
