[Feature request] Support for IndexTTS-2.5 (I'm working on this)

[IIIIIllllIIIIIlllll]

I will do a local adaptation, test it, and then submit a PR (draft).

@IIIIIllllIIIIIlllll Great! I missed the repo update. Bilibili seems to be pretty quiet about this. Is the architecture similar to IndexTTS2?

Update: looks like changes are in GPT and codec. The other components can be reused.

@IIIIIllllIIIIIlllll Whenever that initial IndexTTS-2.5 q8_0 gguf test setup is ready for an early run, please pass the keys over. I’m ready to put it through its paces.
