 Enhancements:
 - Images | DietPi images are now shipped with a trailing FAT partition which contains dietpi.txt and other config files for easier pre-configuration and automation from Windows and macOS hosts. The partition is removed automatically on first boot, after copying all supported config files/scripts. Related CLI flags have been added to our build scripts: "--add-fat-part" for dietpi-imager and "--no-fat-part" for dietpi-build. Many thanks to @dirkhh for implementing this feature: https://github.com/MichaIng/DietPi/pull/6602
-- Images | All our images are now compressed via xz instead of 7z. These are a little easier to handle, especially on Linux hosts, and many flashing utilities allow to flash zx-compressed images directly to disk, without the need to manually decompress them first. As xz compresses files and no directories, the dedicated README.md and hash text files are not included anymore. The hashes for integrity checks within an archive have no real purpose, as the compression algorithms imply hashes internally (CRC64 in case of xz), which are checked and integrity of the content assed as part of the decompression.
