Convert SIXEL to ISOBRL6

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.

The ISOBRL6 file extension, short for ISO/TR 11548-1 Braille 6 dots, is a digital format used to store and represent Braille characters and documents. It is an enhanced version of the original ISOBRL format, offering improved features for displaying textual and symbolic information in Braille. This format supports a wide range of Braille codes, character sets, and languages, making it suitable for Braille printing, displays, and electronic readers for visually impaired individuals. The ISOBRL6 format adheres to the international standard ISO/IEC 14496-28, ensuring compact and portable representation of Braille text for electronic systems.
