The new smaller Llama 3.2 1B and 3.2 3B models have tied weights - so Levanter throws an error currently if we try to import these models. https://huggingface.co/meta-llama/Llama-3.2-1B-Instruct/blob/main/config.json  This adds HF support for that argument and just switches to using embedding.unembed when Embeddings are tied!
