Convert mef to sixel

What is the difference between .mef and .sixel?

Description: The MEF file format stands for Mamiya RAW Image and is used to store images captured by Mamiya digital cameras, a brand known for its medium format cameras and lenses. Similar to other RAW image formats, MEF files contain all the data captured by the camera's sensor, without any in-camera processing or compression. This allows photographers to have greater control over photo editing, enabling them to adjust exposure, white balance, and other parameters without loss of image quality.; 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.
