--resume-from functionality

[lakshya-4gp]

I would recommend following changes, which

1. Currently, even if auto_resume is not mentioned in the config, find_latest_checkpoint command will still run as cfg.get("auto_resume", True) would return True if not found.

2. would give preference to cfg.resume_from over cfg.auto_resume [Optional]

Thanks for your advice. I think just changing the default value of auto_resume to False should works. I will update it.
