// Simply print out the logo (with white background) onto stdout.
// The format is Sixel, which is part of the VT340 standard, is using DCS (device control string)
// to submit the data through stdout.
// Non-supporting terminals will simply ignore the DCS sequence, resulting into a no-op.
//
// The logo was converted from the docs/logo.svg using:
// inkscape -w 128 -h 128 docs/logo.svg -o solc/logo.png
// img2sixel solc/logo.png solc/logo.sixel
// Since the DCS payload consists exclusively of ASCII printable characters, I decided to embedd it
// as a string directly.
