Script Preparation code:

  var dataBuffer = new Uint8Array(data);

    for (var i = 0; i < view.byteLength; i += 4) {
      // Using getUint32 reduces the number of iterations needed (we process 4 bytes each time)
      var value = view.getUint32(i)
      // toString(16) will give the hex representation of the number without padding
      var stringValue = value.toString(16)
      // We use concatenation and slice for padding
      var padding = '00000000'
