cps.macros.flags

Use this flag for debugging of async transformation process.

   implicit val = cps.macros.flags.DebugLevel(10)
   async{
      ....
   }

will output ton of traces during macro translation.

if implicit object of type PrintCode.type is defined, than macro print code befroe and after expansion

if implicit of type PrintTree.type is defined, them macro print ast tree before and after macro transformation.

if implicit object is defined, than macro use runtime await for CpsRuntimeAwait (work only on JVM with JDK-19 early access, which inclipe project loom support)
