Support for Llama-3-Nemotron models (#377)

* conflict resolution

* Changes to make work and add longrope support

* Changes to n_attention_wv rule

* Untested support of 253B

* DeciLMCausalModel now reads rope_theta from config.json properly

* Remove errant Granite mentions

* Better n_attention_vw rule

* Update vocab.py
