OLED_RST not necessary on v2.0

[jsvgoncalves]

I just tested on my chip and it seems that OLED_RST (or pin 16, for that matter) do not exist and as such is not required to set up. Is this so?

If so, then this portion could be removed from the setup() in the example:

Our suggestion is not to delete this line of code, because the SSD1306 screen does not work properly. Of course, if all the modules are working properly after you modify them, that's right.
