Sixel support #34
Description
Sixel is a bitmap graphics format that is supported by a lot of terminals. It allows you to print pictures in the terminal, and it would be a great way to improve the feature set of this framework.
As far as I can tell, this framework uses xterm.js. Although xterm.js doesn't support Sixels directly, there is an MIT-licensed extension that could enable it (xterm-addon-image).
