[pyenergyplus] system exit called when energyplus can't run

[antoine-galataud]

Issue overview

When invalid arguments prevent EnergyPlus binary from running, system exit (1) is called and api caller program is interrupted.

Example:

from pyenergyplus.api import EnergyPlusAPI

if __name__ == "__main__":
    api = EnergyPlusAPI()
    exit_code = api.runtime.run_energyplus(api.state_manager.new_state(), "wrong")
    print("exit:", exit_code)

Output is:

ERROR: Multiple input files specified:
  Input file #1: w
  Input file #2: r
  Input file #3: o
  Input file #4: n
  Input file #5: g
Type 'energyplus --help' for usage.

then script exists with code 1. Last print statement isn't executed.

In library mode, the caller program should be responsible for calling system exit.

Details

• Platform: Ubuntu 20.04 LTS
• Version of EnergyPlus: v9.4.0

I find this really annoying too. It kills my jupyter notebook whenever it doesn't work, which defeats the purpose of using a notebook.
