Expose `KMZLayer.parse` function for FileReader usage

[meihuisu]

This allows uploading of local kml/kmz file with FileReader

function uploadKMZFile(urls) {
  var reader = new FileReader();
  reader.onload = function(event) {
      var result = reader.result;
      var kmz = L.kmzLayer().addTo(map);
      kmz.parse(result, { name: urls[0].name, icons: {} });
  };
  reader.readAsArrayBuffer(urls[0]);
}
