Add call graph

[psolyca]

Is your feature request related to a problem? Please describe.
No.
Just a new feature to help the RE.

Describe the solution you'd like
I would like to use a call graph app within VSCode or be able to launch one.
I have found that androguard could be used.
Also it is a 'many' features app.
I did not fully tested it, just the call graph.

Additional solution
By the way, it is a Python app with many dependencies (I am more a Python afficionado).
There is also these following :

• FlowdoidCG dependencies are integrated - old
• apkinspector lots of big dependencies - very old
• apk-static-xref ruby dependend - very old
• AP_CG Java based - old - must alter Main.java file to register the apk
