Subject: [PATCH] Fix incorrect block progress calculation in header download
 log

  tip_height is 0-indexed, so the total header count is tip_height + 1.
  Using tip_height as the denominator caused >100% progress (e.g. 200%
  with 2 blocks) and division by zero when tip_height is 0.

  Fixes Blockstream/electrs#197
