Allocate data with Data_Make_Struct so Ruby owns the memory as soon as the object is created. This avoids leaking the ALLOC_N buffer if Data_Wrap_Struct raises while allocating the Ruby object.
Prefer TypedData for Buffer, Packer, and Unpacker objects so the extension builds with Ruby 4.1 where the old Data_* access macros are no longer available. Keep MessagePack_Buffer_wrap as a wrap operation because it exposes an existing embedded buffer.
