We observed that the Unigram model's cache introduces significant contention overhead under multi-threaded scenarios. To mitigate this, we made the Unigram cache optional following BPE model's approach. Users can now disable it via
resize_cache(0). Additionally, we addedTokenizerImpl::get_model_mutto obtain a mutable reference of model.
