We need to think through the ideal API for this and #20 as well, but something like:

execa('./cli', [], {
  transforms: {
     // shortcut to a built-in transform we provide
    stdout: 'line',

    stderr: through2(function (chunk, encoding, callback) {
      // custom processing here
    })
  }
}).then(function (result) {
  result.stdout;
  // => an array of lines

  result.stderr;
  // => an array of whatever the custom transform emits
});

Re-opening since transforms can currently only return a string or a Uint8Array. The underlying stream's objectMode is always false.
