[ANN] library updates

[dmiller2718]

Minor updates to several libraries.  Mostly this was to change the target frameworks in the DLL delivered by nuget to be netstandard2.0 and 2.1.  These DLLs only contain text file resources, but with this targeting you won't get warning messages about framework mismatch when you use them.

There were some minor changes in the Clojure(JVM) spec libraries -- these have been incorporated.

clr.tools.reader 1.3.4.1

clr.tools.namespace 1.1.0.1

clr.test.check 1.1.0.1

clr.data.generators 1.0.1.1

clr.test.generative 1.0.1.1

clr.specs.alpha 0.2.194

clr.core.specs.alpha 0.2.56
