Ultimate RVC: A working alternative to this project

Seeing as this project is now (more or less) officially deprecated, I thought I would throw my hat in the ring too. I have been working on a fork of this project, known as [Ultimate RVC](https://github.com/JackismyShephard/ultimate-rvc), now for more than a year. It has a lot of new features and more importantly, it is stable and maintained. In case you have any issues or questions you are free to reach out.
