feat: add DiffRhythm dependencies to ComfyUI requirements

Added all required packages for ComfyUI_DiffRhythm extension:
- torchdiffeq: ODE solvers for diffusion models
- x-transformers: Transformer architecture components
- librosa: Audio analysis and feature extraction
- pandas, pyarrow: Data handling
- ema-pytorch, prefigure: Training utilities
- muq: Music quality model
- mutagen: Audio metadata handling
- pykakasi, jieba, cn2an, pypinyin: Chinese/Japanese text processing
- Unidecode, phonemizer, inflect: Text normalization and phonetic conversion
- py3langid: Language identification

These dependencies enable the DiffRhythm node to load and function properly in ComfyUI, fixing the "ModuleNotFoundError: No module named 'infer_utils'" error.
