bench: option to start output only at a certain time
Problem to solve with the new feature
For longer simulations, one might be interested only in the output of the last part of the simulation duration. This can be achieved by splitting into two simulations (one without output) and transferring the state between them but I think a direct option could be useful in many cases.
Proposal
Include an option --start-out
in bench.
Testing
(What risks does this change pose? How might it affect the quality of the software? What additional changes to tests will be needed?) Can't see any right now.
