Enforce time/memory limits for model solution during outgen

[otargowski]

Is your feature request related to a problem? Please describe.
If the model solution has a serious bug and for example eats up all the RAM,
then it will probably get killed along with sinol-make, maybe also the shell
and terminal (this actually happened).

Describe the solution you'd like
The model solution being run with limits from config.yml enforced.
For some weird use cases a cli arg disabling this may be useful, for example
generating very precise results for a problem in which the complexity depends
on the chosen precision.

Describe alternatives you've considered
To complement this, maybe an additional limit for how many solutions should run in
paralell based on the amount of available ram? Idk if this is already implemented.
