Subject: [PATCH] Reset before initialisation of the SSD1306 when OLED reset
 pin is set

If an OLED Reset pin has been selected using the PIN configuration, it makes sense to also send a reset signal to this pin before initialization of the display. The current value 0 doesn't send this signal, not even when a reset pin has been selected. Hence the change of value 0 into reset_pin >= 0. If no reset pin was set, the value of this variable is -1.
