Aoi based inference

This PR:

• adds new inference logic
• implements the real inference logic into the endpoint in a limited sense. That is - for now providing the predefined aoi and image uri

In general you should use logging instead of printing to stdout, but all those print calls look like debugging to me.

You're right. I forgot to remove the print statement meant for debugging.

Sorry for the late review but I'm in Switzerland at my company's head quarter.
