Progress display messes up on console input

[erhhung]

I've noticed that with any of the examples, but especially multi-bar ones, that if I start typing while the progress bars are moving, the console just gets filled with uninterpreted ANSI escape sequences on every tick, and the bar rendering completely breaks.

I don't see a need to accept typed input during progress monitoring, except perhaps ESC to cancel, but the console rendering positions should not break down.

I'm running the examples in a Mac Terminal window with Bash if that makes a difference.

Perhaps this can only be handled outside of the core component. I've solved this issue by putting stdin into raw mode and explicitly handling keys like ESC and SIGINT before I begin the concurrent progress bars:

const {stdin} = process;

stdin.setRawMode(true);
stdin.setEncoding('utf8');
stdin.on('data', (key) => {
  if (key === '\u001b' || // ESC
      key === '\u0003') { // Ctrl-C
    process.exit();
  }
});
stdin.resume();

As I'm just writing a CLI app, I just terminate the process, but you could resolve a promise or do some other signaling if you wanted to stop or pause the processing.
