Failed to compile model with enums and nested bus objects

[Thandre]

I have problems compiling a model that contains enums and nested bus objects. It seems that the struct_parser.py doesn't support this. When I try to implement some exceptions for these types the model compiles but it crashes when I read out the model (e.g. with get_block_param()).

I have attached a model that contains the things to reproduce the error.
