`transformers.Trainer` variant of `UnslothTrainer`

[lmg-anon]

This isn't a major issue, but I'm unable to use code for transformers.Trainer with UnslothTrainer without modifying Unsloth's code. Currently, UnslothTrainer inherits from SFTTrainer. It would be nice if there was another class like UnslothTrainer that inherited from transformers.Trainer instead.

Oh good point! I was thinking of doing a UnslothWrap(Trainer) type wrapper
