C++ version

[DDATT]

I have created a repository for implementing the VITS2 model in C++ at VITS2-CPP. Hope it can be helpful to everyone.

Thanks for sharing! How much faster it gets?

I am currently hosting my VITS2 as onnx running on nvidia Triton - it runs quite smooth.

I haven't tested with a GPU yet. But with Intel Core i5-8400 2.8GHz x 6 CPU, on Linux env, it takes 2.5 seconds to generate a 10-second audio, which is almost similar to the Python version (2.2 seconds to generate from the same input).
