v2.33.1: The skill says when a list or ranking is missing records

• You're told when a list is missing records. Some stacks return the same record on two pages,
  which leaves another out. The skill now says how many are missing, for a spreadsheet export too,
  instead of presenting the list as complete.
• A ranking that may be incomplete is labelled. It is shown as provisional, never as "the top
  10", and the skill offers to narrow the question so the ranking can be read in full.
