v1.0 版本的错误问题解决方法

After version 1.0, the model directory has been moved to the `asset` folder under the software root, instead of the `models` folder. By default, the model files will be automatically downloaded to the `asset` folder. If the download fails due to network issues, please click this link https://GitHub.com/jianchang512/ChatTTS-ui/releases/download/v1.0/all-models.7z to manually download the compressed package. After downloading and extracting the package, you will get an `asset` folder containing the model pt files. Simply copy the `asset` folder from the compressed package to the software root folder to overwrite the existing `asset` folder with the same name.
