wandb logger args

[ysjprojects]

Addresses #1909.

More fine-grained logging args: supports wandb args specifying run_name and group_name for now.

@dataclass
class LogArgs:
    """Logging-related arguments"""

    wandb_project: Optional[str] = None
    """Wandb project name"""
    wandb_run: Optional[str] = None
    """Wandb run name"""
    wandb_group: Optional[str] = None
    """Wandb group name"""

New LoggerArgs as it fits neither TrainArgs nor EvalArgs. We can expand on this in the future.

wandb is not the only one or default logger so we shall not name it with generic LogArgs
