Convert RW2 to FLIF

The RW2 file extension stands for Panasonic Digital Camera Raw Image File, primarily used by Panasonic LUMIX cameras. This format captures uncompressed image data directly from the camera's sensor, ensuring high-quality images suitable for professional editing. Introduced with models like the LUMIX LX3 and LX5, RW2 files are based on the TIFF specification and are similar to other raw formats like RAW and RWL. These files can be opened and edited using various software.

The Free Lossless Image Format (FLIF) is a lossless image compression format designed to outperform other formats like PNG, lossless WebP, and JPEG 2000 in terms of compression ratio. Introduced in 2015, FLIF uses MANIAC (Meta-Adaptive Near-zero Integer Arithmetic Coding) for efficient compression, making it suitable for various image types without quality loss. Despite its advantages, FLIF development ceased as it was superseded by JPEG XL.
