This patch adds images to the mosaic folder entries: it uses the first cover according to the current sorting chosen by the user.
If you want to use your own folder cover, please add an image file in the folder named `.cover.jpg`, `.cover.jpeg`, `.cover.png`, `.cover.webp`, or `.cover.gif`.
You'll find its options under <sub><img src="img/appbar.navigation.svg" style="width:2%; height:auto;"></sub> **🞂 Settings 🞂 Mosaic and detailed list settings 🞂 Folder name centered** and **Crop folder custom image** and **Show folder name**
