Enable saving the entire simulation state to disk and restoring it again #757

This feature is desired in the OptiStress project, where we will need to simulate the same system many times in a loop with parameter variations. It will save a lot of time since we can start each simulation from a “warmed up” state.

Depends on #756 and #768.

Suggestions for suitable storage formats are welcome. Note that according to the FMI spec, each subsimulator does its own serialisation and deserialisation, and all the co-simulator sees are binary blobs. So the format needs to support storage of arbitrary binary data.
