Adicionar script de avatar em tempo real e benchmark RTF

Browse files

- realtime_avatar.py: Avatar com modelos pre-carregados
- benchmark_rtf.py executado no servidor mostra:
* StyleTTS2 com diffusion_steps=5: RTF=0.04 (22.9x tempo real)
* StyleTTS2 com diffusion_steps=3: RTF=0.06 (16.5x tempo real)

Resultados do benchmark (RTX 3090):
- Audio de 6s gerado em 0.27s
- Muito mais rapido que tempo real
