Subject: Final steps for annotations getting from chisel to firrtl (#405)

Pass transforms along with Annotations when calling firrtl compiler
This introduces new requirement that firrtl.Transform subclasses (that are associated with an annotation) do not have parameters in their default constructor
Add new test for NoDedup annotation that shows how to annotate a module instance---
