Serialization: cannot deserialize files saved before the last major refactoring

**Describe the bug**
I have written files with some lattice data before the last refactoring of serialization, which cannot be open anymore. I get the following error:

```
julia> load("Schreibtisch/Projects/Storage/enum_gen/tmpFermat.mrdi")
