Usage example in README.rst refers to non-standard Adafruit module

[SAK917]

The Usage Example code in README.rst refers to a module possibly used during development?

Line 5: import mdroberts1243_displayio_sh1107

and

Line 19: display = mdroberts1243_displayio_sh1107.SH1107(display_bus, width=WIDTH, height=HEIGHT)

I believe the correct reference should be adafruit_displayio_sh1107.

I am happy to make whatever change you think would be appropriate and submit a PR if it will help.
