[Feature] IndexTTS2

[frink]

IndexTTS2 is the most emotional realistic TTS I've heard. Any hope of porting that over?

My next step should be Qwen3-TTS。 IndexTTS distilled audio data is needed very badly!

The Qwen suite is very lifelike. (Love their VD) However, it has no emotional prompting like IndexTTS2. I've generated stuff with both and IndexTTS2 just makes Qwen sound kinda stilted.
