 Wav2Vec2 model HPU configuration  This model only contains the `GaudiConfig` file for running the [Wav2Vec2](https://huggingface.co/facebook/wav2vec2-base) model on Habana's Gaudi processors (HPU).  **This model contains no model weights, only a GaudiConfig.**  This enables to specify: - `use_habana_mixed_precision`: whether to use Habana Mixed Precision (HMP)     - `hmp_opt_level`: optimization level for HMP, see [here](https://docs.habana.ai/en/latest/PyTorch/PyTorch_Mixed_Precision/PT_Mixed_Precision.html
