* Generalize Zinc worker

- Compiler bridges can now be either pre-compiled or on-demand-compiled
- Scala library/compiler jar discovery is now configurable
- Zinc compiler cache is now configurable, rather than being hardcoded at n=1

* .

* update constructor args

* remove duplicate util/AggWrapper.scala file

* fix
