Summary: Refactors MapBuffer-related `primitives.h` to be namespaced with `MapBuffer` class, to avoid name collisions and confusion later on. Most of the size constants are moved to relevant .cpp files or updated to use `sizeof`. Additionally, adds a little bit of documentation about `MapBuffer` serialization format.
