Adds rotate(bool) to official SSD1306 driver.

The existing init_display() method initialises the screen in the normal orientation.
This PR adds the ability to rotate the display 180 degrees, by remapping the segments and flipping the common output direction. Uses commands SET_COM_OUT_DIR and SET_SEG_REMAP.

Note: changing the common output direction updates the display immediately (mirrored vertically). After remapping the segments, you need to call show() again to repopulate the display memory with the pixel data in the reverse order (mirrored horizontally).

Testing on TinyPICO - ESP32

# MicroPython v1.14 on 2021-02-02; TinyPICO with ESP32-PICO-D4
from machine import Pin, I2C
import ssd1306
i2c = I2C(1, sda=Pin(21), scl=Pin(22))
display = ssd1306.SSD1306_I2C(128, 64, i2c)

# micropython logo
display.fill(0)
display.fill_rect(0, 0, 32, 32, 1)
display.fill_rect(2, 2, 28, 28, 0)
display.vline(9, 8, 22, 1)
display.vline(16, 2, 22, 1)
display.vline(23, 8, 22, 1)
display.fill_rect(26, 24, 2, 4, 1)

# some text
display.text('MicroPython', 40, 0, 1)
display.text('SSD1306', 40, 12, 1)
display.text('OLED 128x64', 40, 24, 1)
display.show()

# rotate 180 deg
display.rotate(True)
display.show()

# rotate 0 deg
display.rotate(False)
display.show()

Hi there! I was using ESP32 with 1.17 firmware and this SSD1306 lib, however the rotation method can work properly. It just, won't do anything. Can you have a dig into this? Thanks!
