ScenarioPlayer destructor memory corruption

[ebadi]

This is probably because of incorrect translation of methods by pybind11.

import pyplayerbase
print("Start")
player = pyplayerbase.ScenarioPlayer(
    ["filename", "--window", "60", "60", "800", "400", "--osc", "./esmini/resources/xosc/cut-in.xosc"])
print("End")

To partially resolve the issue, both pyscenarioengine and pyplayerbase have to be imported

import pyplayerbase
import pyscenarioengine

Results in:
