Support timeout for running simulations with C-API

[schmoelder]

(Not sure if this is a CADET-Python issue)

When using the CLI via Python, we can specify a timeout via:

data = subprocess.run(
    [self.cadet_path, str(simulation.filename)],
    timeout=timeout,
    capture_output=True
)

Is something like this also generally possible when running simulations via the C-API?
It can be quite useful at times...
