[FEAT] Create AI CLI

[sconetto]

Create an easy way to use the assistant.

Expected Behavior

The assistant should have a friendly interface to colour given images

Current Behavior

The process is linear, from training to colouring without interface with the user.

Possible Solution

To create a CLI.

I might be implementing soon a better CLI which allows the user to color one specific image by passing its path as an argument
