Use scan code for key translation to distinguishi left and right on keyboard

[Ywatcher]

Currently QPanda3D_Key_translation uses type PyQt5.QtCore.Qt.Key as dictionary key values. However, left and right shift etc. cannot be distinguished in this way since these keys are mapped to same name by Qt. Is it a good idea to use integer scan codes instead in the dictionary, so that lshift and rshift can send different messages?
