Binary downloads

When downloading binary data, the data must be a Blob, otherwise the downloaded file will be corrupted. For example, using Axios:

import Axios from axios;
import fileDownload from 'js-file-download';

function download(url: string, filename: string) {
  Axios.get(url, {
    responseType: 'blob',
  }).then(res => {
    fileDownload(res.data, filename);
  });
}
