Convert cff to sixel

What is the difference between .cff and .sixel?

Description: The Common File Format (CFF) is a standardized file structure designed to facilitate the sharing, exchange, and preservation of data across various platforms and applications. It is not tied to a specific domain but is rather a generic format that can be adopted by different types of software and systems for a wide range of data types. The CFF aims to provide a common framework that ensures data interoperability and accessibility, making it easier for users to work with data across different tools without the need for extensive conversions.; Created by Digital Equipment Corporation (DEC), SIXEL is a bitmap image format in an escaped sequence (seen as six pixels high and one pixel wide). You have to convert it into a more accessible format if you don’t have a DEC terminal to view it.
