Convert MNG to SIXEL

The MNG (Multiple-image Network Graphics) file extension is a specialized format for animated images, originating from the creators of the PNG format. Developed in 1999, MNG supports features like image sequences, transparency, and JPEG data embedding, making it useful for complex animations and graphics interchange. Primarily utilized in web applications and multimedia presentations, it offers efficient compression and high-quality visual representation, catering to the needs of graphics-intensive environments.

The SIXEL, or "six pixels", is a bitmap graphics format created by Digital Equipment Corporation (DEC) for their terminals and printers. Initially designed for DEC dot matrix printers like the LA50, it enabled the efficient transfer of bitmap graphics using a series of ASCII characters. Each character represents a 6-pixel high row, making it suitable for 7-bit serial communication. This format was later adapted for modern terminal emulators, extending its utility beyond its original scope.
