This adds scaffolding but no real functionality yet, as part of marapongo/mu#41. I am landing this now because I need to take a not-so-brief detour to gut and overhaul the core of the existing compiler (parsing, semantic analysis, binding, code-gen, etc), including merging the new pkg/pack contents back into the primary top-level namespaces (like pkg/ast and pkg/encoding). After that, I can begin driving the compiler to achieve the desired effects of mu compile, first and foremost, and then plan and apply later on.
