Rewrite pack converter code and add pack schemas

Java POJO's are now generated from JSON schemas meaning they should always be up-to-date. The legacy converters have been moved into a separate package until they get converted. This new structure and systems/supporting APIs backing it makes the library far more powerful and will allow for much greater potential going forward.
