words for OLED-displays
these words are derivated from Jean-Claude Wipplers ssd1306.fs, but that one didn't exactly work with my ssd1306.fs so I had to change the init function. As I was on it I also wrote words for a sh1106 and a ssd1327 OLED-displays. Fortunately this means they all work with jcws graphics.fs. Which is very usefull, since it provides basic graphic and font writing capabilities.
small changes for my ssd1306, the original version from jcw didn't work.
support for sh1106 displays which need a bit different init and is internaly 132 wide organized
support for ssd1327 displays which allows 4 bit grayscale per pixel and bigger resolutions.
