Restarts are running for full time step amount

@chapman39 is already working on this.

Since May 19, 2022.

Cycle is loaded from previous run here:

https://github.com/LLNL/serac/blob/4c19ba966aeed4bc73b3ac5513fbd45eed370451/src/drivers/serac.cpp#L162

but the time step is not adjusted here:

https://github.com/LLNL/serac/blob/4c19ba966aeed4bc73b3ac5513fbd45eed370451/src/drivers/serac.cpp#L201-L203

This should also be something like this:

```
// Initialize/set the time information
double t;
if (restart_cycle) {
t = // grab time from datacoll based on given cycle;
} else {
t = 0;
}
```

This ends up running the following amount of steps on a restart:

(time step of cycle loaded) + full simulation time step amount = too much!

Thanks to @chapman39 for noticing!
