How to access seq id and type strings from ksy file in KSC scala?
Using [this ksy](https://github.com/det-lab/dataReaderWriter/blob/master/kaitai/ksy/animal.ksy) for reference- 

I'm wondering how I can generate, for example `animal_entry_t` , `m_entry`, `weight`, etc. generally? 

Things like `${privateMemberName(id)}` are scoped only within certain functions, and some like `${types2class(typeProvider.nowClass.name)}` return different strings depending on where they are called. 

Is there a consistent way to access the `id`s and `type`s described in a ksy file?
