Androguard v4 incompatibility

[MobCode100]

Since androguard >= v4 has been released, the line from androguard.core.bytecodes.apk import APK will crash, and I'm getting ModuleNotFoundError: No module named 'androguard.core.bytecodes' error. A simple solution for this is to change the requirements.txt to put version limit on androguard e.g. androguard<4 and then run again the pip install command.
