Allow passing arbitrary arguments to the python interpreter

[LarsGavris]

node-python-bridge/index.js

Line 22 in 9b13b40

let ps = child_process.spawn(intepreter, [PYTHON_BRIDGE_SCRIPT], options);

Issue

Hardcoding [PYTHON_BRIDGE_SCRIPT] here prevents users from passing any arguments to the interpreter.

My use case

I want to pass -u to python3 in order to flush stdout after every print.
This way I don't have to manually flush the stdout after (via sys.stdout.flush()) or within (via print(message, flush=True) every print.
