Resolves #278
PyTorch allows to load state dicts with they strict=False argument to ignore missing keys. This is now also supported in optimum-quanto. Before this fix, a KeyError would be raised.
One context where this is important is for parameter-efficient fine-tuning adapters such as LoRA. There, we want to load only a small subset of parameters and leave the other model weights untouched. This requires non-strict loading.
