547 Prototype to make library types singleton instead of static on 1.0

[baseTwo]

DO NOT MERGE THIS. Performance testing needs to happen to compare to static library types, and if found to be comparable enough, can be cherry picked back into PR #548

[DamienMosier]

Ran a performance test on a few measures with a few large decks and performance is comparable between static and singleton.

Part of our public API could be something like this:

public static IServiceProvider AddLibraries(this IServiceProvider isp, LibrarySet libraries)
{
  ... compile the library set to assemblies, and then register their types as singletons
}
