Integrate EP feature

[AlexVanMechelen]

This PR adds:

• A cfg property returning the address of the EP

I first tried:

binary['cfg']['model']['project']['entry']
ERROR: 'CFGModel' object is not subscriptable

Then tried:

binary['cfg']['_CFG__project']['entry']
KeyNotAllowedError: '_CFG__project'

Now:

binary['cfg']['entry']
