How to use the ky/umd.get function in ky

const tasks = remoteFiles.map(({ url, metadataPath, ...options }) => cb => {
    cb = once(cb)
    const start = Date.now()
    console.log('Requesting', url)
    // I tried doing this by adding streams to the zipfile, but it's really hard
    // to catch errors when trying to download an image, so you end up with
    // corrupt files in the zip. This uses a bit more memory, but images are
    // only added once they have downloaded correctly
    ky.get(url)
      .arrayBuffer()
      .then(arrBuf => {
        console.log('Req end in ' + (Date.now() - start) + 'ms ' + metadataPath)
        zipfile.addBuffer(Buffer.from(arrBuf), metadataPath, {
          ...options,
          store: true
        })
        cb()
      })
      .catch(err => {
        missing.push(metadataPath)
        console.log('Error downloading file ' + metadataPath, err)
        cb()
      })
