Adding a feature: token info flag option

[arilloid]

Description

Adding a new command-line flag --token-usage/-t to be able to quickly check the amount of tokens that have been sent with the prompt and received from the LLM in completion object.

This can help you manage the costs of the API requests, and improve the efficiency of interactions with a LLM.

Implementation

Implementing this feature would require:

• Adding the code for parsing the --token-usage/-t option flag argument from the command line in codeMage.py.
• Modifying translator.py to check if the flag was provided and, if present, output the token usage information to stderr. (Information about the token usage can be found inside the completion object).
