feat: add logfire as output method

[inimaz]

Goal

Open the discussion on how codecarbon could send the output to logfire, a new monitoring framework https://docs.pydantic.dev/logfire/

How to use this branch

pip install logfire
logfire auth

This redirects to a page where you can log in with your github user.

Once your logfire account is created, run the script:

hatch run python examples/logfire_metrics.py'

Output

Example of the output that I obtain

As discussed @SabAmine, here it is a rough example using the log output. What do you think?

@SaboniAmine It should be ready to merge. Now it uses the composite output handling coming from master. And it calls logfire.configure() to setup the main instance of logfire (see last commit).
