Update .gitattributes for optimal handling of large and text files

This commit updates the .gitattributes file to optimally handle different file types used in the project.

Key changes include:

1. **Large File Storage (LFS)**:
- Tracks large model, data, and compressed files using Git LFS.
- Includes common formats such as `.bin`, `.h5`, `.npy`, `.pt`, `.safetensors`, and others.
- Includes `.m` and `.mat` for MATLAB files.

2. **Text Files**:
- Configures `.py` for Python scripts as text.
- Configures common text formats such as `.md`, `.toml`, and `.yml` as text.

This ensures that the appropriate file types are stored and managed correctly.
