Added JSON latents creation

- System automatically creates `.json` latent files alongside voice samples
    - Latents are voice characteristics extracted from audio
    - Generated on first use of a voice file
    - Stored next to original audio (e.g., `broadcaster_male.wav` → `broadcaster_male.json`)
    - Improves generation speed for subsequent uses
    - No manual management needed

-    ### Single Voice Setup (Wav/MP3)
+    ### Single Voice Setup
     - Place WAV/MP3 files in `/alltalk_tts/voices/`
     - Use descriptive filenames (e.g., `broadcaster_male.wav`)
     - Files appear as individual voices in interface
     - Best for quick testing or simple use cases
 
-    ### Multi-Voice Sets (Wav/MP3)
+    ### Multi-Voice Sets
     - Create folders in `/alltalk_tts/voices/xtts_multi_voice_sets/`
     - Add multiple samples per voice
     - System randomly selects up to 5 samples
     - Better for consistent voice reproduction
     - Example: `/voices/xtts_multi_voice_sets/broadcaster_voice/`

+    - Allows sharing latents without original audio
+    - Same format as automatic latents
