`state.get(i)` returns the value at `i`, not the record at `i`

[cowboyd]

If you have a record with the value "bob", you expect state.get(0) to return a record like:

{
  offset: 0
  isPending: false,
  isRejected false,
  isSettled: true,
  content: "bob"
}

Instead you see "bob"

If that's the case then we can forget about returning state.pages since that's what we used to compute the page numbers in the color-demo. We can easily get the page numbers by using the Math.floor(record.offset / pageSize)

If, of course, we want to remove the notion of pages. It can wait for the time being.
