Refacto to use Lightning CLI

[LBerth]

• rm TorchDataLoaderSettings class
• rm ArLightningHyperParams and define all these variables as attributes of the ARLightningModule
• Add bin/main.py as alternative to bin/train.py, using lightning CLI to launch fit : python bin/main.py fit --config bin/config_test_cli.yaml or python bin/main.py test --config bin/config_test_cli.yaml.
• Add yaml file config_test_cli as basic titan config for CLI
• rm old file ideas/test_argpase.py (old alternative to CLI)
• Nota bene: bin/train.py still works, but inference.py, test.py and gif comparaison will probably not work but will be replaced in future PR.

Very cool, nothing that bothers me, the code seems even more readable (I even seem to understand what cli is about 😅 )
