We now have this new daffodil-macro-lib module.

In the projects/build.scala, it is not listed as "nopub". It seems to be needed to be published, but I don't know why it would be needed.

In creating a scala build for a data format (where the jar created contains the DFDL schema, and can run TDML tests), there is a dependency on the daffodil-tdml library, and this transitively ends up requiring the macroLib, so fails if the projects/build.scala is changed so that macroLib is "nopub".

So the task here is figure out why, so that macroLib truly is only needed at scala-compile time for daffodil, and not needed when other consumers of daffodil libraries are used.
