Enhance model building process and update README for Windows setup

- Added functionality to download additional required files, including config.json, during model initialization in models.py.
- Improved module import process for better clarity and organization.
- Included a test for the phonemizer to ensure functionality.
- Updated README to provide specific instructions for enabling Developer Mode or running Python as Administrator on Windows for optimal performance and symlink support.

   - macOS: `brew install ffmpeg`
 
+### Windows-Specific Requirements
+For optimal performance on Windows, you should either:
+1. Enable Developer Mode:
+   - Open Windows Settings
+   - Navigate to System > Developer settings
+   - Turn on Developer Mode
+   
+OR
+
+2. Run Python as Administrator:
+   - Right-click your terminal (PowerShell/Command Prompt)
+   - Select "Run as administrator"
+   - Run the commands from there
+
+This is needed for proper symlink support in the Hugging Face cache system.
+If you skip this, the system will still work but may use more disk space.
