Hi, is the quality option in the compress function OK?

https://github.com/foliojs/brotli.js/blob/master/compress.js#L18=

  } else if (typeof opts === 'object') {
    quality = opts.quality || 11;
    mode = opts.mode || 0;
    lgwin = opts.lgwin || 22;
  }

README says quality could be 0, but then it should turn into 11. My tests confirm that 0 works like 11.

Where is a mistake? I am extremely sorry if I messed up something
