This pull request adds the vertical scrolling definition command for the ILI9341 (see section 8.2.26 of the datasheet), which can be used in conjunction with the vertical scroll command already implemented in the library (setScroll). The vertical scrolling definition command modifies the scroll feature behavior, allowing for certain rows to be scrolled and certain rows to stay in place.
