Use row and column remapping to change either row or column addressing for each orientation. This removes the need to reverse the drawing direction of either x or y in the drawing routines. However in the 90 and 270 case x and y must still be swapped. Also, rename the SSD1306 remapping command names so they are more descriptive.
