* ssz: move ref support outside Instead of allocating ref's inside SSZ, move it to separate helper: * makes `ref` allocations explicit * less magic inside SSZ * `ref` in nim generally means reference whereas SSZ was loading as value - if a type indeed used references it would get copies instead of references to a single value on roundtrip which is unexpected TODO: EF tests would benefit from some refactoring since they all do the same thing practically..
