v6.12.0

Added

• Added cursor.kill method

  Cursors that have not yet been fully depleted can now be killed using the
  cursor.kill method. Note that this method has no effect if the cursor
  is already depleted.

• Added cursor.nextBatch method

  Cursors normally fetch additional batches as necessary while iterating
  over the individual results, this method allows consuming an entire batch
  at a time.
