64x48 oled support

[deafloo]

Description

Naturally supports 0.66" (aka 64x48) OLED displays. Previously, the displays had to be implemented by OLED_DISPLAY_CUSTOM option.
Since the position of pixels in the controller memory matrix varies based on manufacturer, the OLED_COLUMN_OFFSET now works with sh1106 and ssd1306 controllers.
