unknown architecture issues on DeepSeek-R1-Distill-Qwen-1.5B-Q2_K.gguf

```dart
error loading model: unknown model architecture: 'qween2'
llama_load_model_from_file: failed to load model
flutter: [AubAi] llama_new_context_with_model(model, cparams)
Lost connection to device.
```

it works properly for `tinyllama-1.1b-chat-v1.0.Q2_K.gguf` but for this model ` DeepSeek-R1-Distill-Qwen-1.5B-Q2_K.gguf` it says unknown architecture
