This PR does a number of things:
1. Renames the oled_i2c example to sssd1306_i2c to match other example folder
names that use the device name
2. Merge code from another ssd1306 exmaple that was sitting in another PR
3. Add a few more demo parts to the code for extra fun.
4. Couple of bug fixes that were reported in original code to fix handling different
display sizes, so code now works for 32 and 64 pixel height displays by changing
a define at top of code.
adc/microphone_adc - Read analog values from a microphone and plot the measured sound amplitude.
i2c/bmp280_i2c - Read and convert temperature and pressure data from a BMP280 sensor, attached to an I2C bus.
