Adding the function to pause and resume simulations

[NaraSakamoto]

Dear Sim4life team,

Please excuse me for the lay terms. Given that some simulations may take hours to run, I wonder if it would be possible in future updates to add a function to pause a simulation and write current intermediate solution to file, which can be loaded back later and resumed.
This would be particularly helpful in the situation of sharing a limited number of solver licenses among a team and a short new simulation needs to run while the license is taken up by a long simulation. Thank you!
