py-xlsxwriter: updated to 1.1.7

Release 1.1.7:

* Added docs on :ref:object_position.

* Added fix for sizing of cell comment boxes when they cross columns/rows that
  have size changes that occur after the comment is written.

* Added fix for the sizing of worksheet objects (images, charts, textboxes)
  when the underlying cell sizes have changed and the "object_position"
  parameter has been set to 1 "Move and size with cells". An \ 
additional mode 4
  has been added to simulate inserting the object in hidden rows.

* Added object positioning for charts and textboxes, it was already supported
  for images. Note, the parameter is now called object_position. The
  previous parameter name positioning is deprecated but still supported
  for images.
