Ess ≠ Goal

• Fixed a space leak and made some of the commands faster by making use of
  parallel-io and using
  pragmas; INLINE, INLINABLE and SPECIALIZE.
• Removed the --dir option from all commands. The current working directory
  is used instead.
• The mask-track command has been split up into smaller commands;
  mask-arrival, mask-bonus, mask-effort, mask-lead and mask-reach.
  Each deals with separate aspects of masking.
• Avoid calculating impossible means when the data set is empty. These were
  seen as huge negative numbers before the fix.
• Show the flying and scored fixes for pilots that have had their tracks
  downloaded for the map.
• Show the effective reset in the penal table when the pilot is too early.
• Move the penal tab to the top-level with its own children; Jump-the-Gun
  & Auto, Ess ≠ Goal and Manual.
• Under Basis | Pilots, put each kind of penalty in its own panel.
• Show toll, rebate and fee to explain how the points after applying the
  jump-the-gun penalty are not less than minimum distance.
• Score the penalty for making Ess but not making goal.
• Show tasks stopped and cancelled in the task list.
• Only show the extra reach via glide column for stopped tasks.
• Don't dislay a chunk distance in the effort table for pilots that don't land
  out.
• Parse FsCompetition/@utc_offset whether or not it has a leading sign for
  both integers and floats.
• Fixed a bug where looking up a chunk for effort failed because of rounding
  then the misplaced pilot got zero points for effort.
• Only the *.fsdb and folders for track logs are left in the root folder since
  the input, output and working files of flare-timing moved to the dot folder
  .flare-timing. Likewise files for comparison have moved from the root to
  .flight-system and .air-score. Add a Compare top-level tab for the
  comparisons between scores.
