unused data & request sets

[apttx]

• remember which files were requested in recording mode
  • if reliable: remember the timestamp & create a set of requests based on how close they were together.
• before sigint? output the files that weren't used to the console

const sensitivity = 3
timestamps.map(timestamp, index, values) => {
  const previousTimestamp = values[index - 1]

  if(previousTimestamp === undefined) {
    return 0
  }
  
  const result = Math.pow(timestamp - previousTimestamp, sensitivity) / previousTimestamp

  return result
})

seems sensible. split at values above 1 (~30s between)
