refactored optionally verbose system calls in python interface

[tudoroancea]

Pursuing the efforts of PR #928, I refactored all the system calls in the python interface by introducing the following utility function:

def verbose_system_call(cmd, verbose=True):
    return call(
        cmd,
        stdout=None if verbose else DEVNULL,
        stderr=None if verbose else STDOUT
    )

Hi 👋 changes look good to me, could you rebase on master?

[tudoroancea]

@sandmaennchen I just did and some of the unit tests fail, and I don't know why yet. I will investigate it as soon as I manage to get them run locally.
In the meantime, do you have any idea what might make the tests fail?

Hi, you can reproduce the error by running the examples minimal_example_sim_cmake.py and extensive_example_sim.py.

This call raises the error, not sure why though, running the command string works fine for me.
