Support for binary response / hex output:

[franky436]

Before “ws.send(programOptions.execute);” add:
ws.binaryType = "arraybuffer";

For hex output use:
wsConsole.print(Console.Types.Incoming, buf2hex(data), Console.Colors.Blue);

p.s.
function buf2hex(buffer) { // buffer is an ArrayBuffer
return [...new Uint8Array(buffer)]
.map(x => x.toString(16).padStart(2, '0'))
.join('');
}

p.s. buf2hex output may then be used like this:

wscat -c ws://1.2.3.4/api/something -w 0 | xxd -p -r | protoc --decode_raw
