- Adds "still_streaming" to shared module for extensions to know if generation is complete
- Changed TTS extension with new options:
- Show text under the audio widget
- Automatically play the audio once text generation finishes
- manage the generated wav files (only keep files for finished generations, optional max file limit)
- [wip] ability to change voice pitch and speed
- added 'tensorboard' to requirements, since python sent "tensorboard not found" errors after a fresh installation.
