v1.1.2

Changed

• Update check simplified: UpdateCheck is a plain boolean in
  RedisExcel.json ("UpdateCheck": true, default on) and a single worksheet
  function, RedisUDFUpdateAvailable(), returns TRUE/FALSE. The intermediate
  { "enabled": ... } shape and the RedisUDFUpdateInfo matrix from v1.1.1
  are gone. The check runs in the background at add-in load and refreshes at
  most every 6 hours when the function recalculates; it never blocks Excel.
