How to use the pako/lib/zlib/inflate.inflateInit2 function in pako

function inflater (emit) {
  let stream = new ZStream()

  return function (data) {
    if (data === undefined) return emit()

    let start
    stream.input = data
    stream.next_in = 0
    stream.avail_in = stream.input.length

    let status, output
