Implement two unpacker apis on the structs. One read only and one with a packer state.

It would be nice to have two unpack methods for all structs

• Unpack(u *packer.Unpacker)
• UnpackTodoFindAGoodName(data []byte)

The problem with these byte slices is that they are often not meant for streaming, meaning, your payload may only contain the actual object and not more.
