This removes memory management from the class; unifies the types used throughout the code using it; and simplifies it all greatly. Also this changes errors handling. Prevoiusly setting errors to parser didn't handle case when no parser was passed to SbiBuffer ctor, as BufferTransformer did, and could dereference nullptr.
