Needs further fixing to be warning-free on 9.0 while working on 8.x.

On 9.0, the current version prints warnings at import:
```
Adafruit CircuitPython 9.0.0-rc.1-1-g7e7b2a4154-dirty on 2024-03-17; Adafruit Macropad RP2040 with rp2040
>>> import adafruit_displayio_ssd1306
FutureWarning: FourWire moved from displayio to fourwire
FutureWarning: I2CDisplay moved from displayio to i2cdisplaybus
FutureWarning: I2CDisplay renamed I2CDisplayBus
FutureWarning: Display moved from displayio to busdisplay
FutureWarning: Display renamed BusDisplay
```
this is related to how an attempt was made to fix this, but it's not quite right because of how the try/import/except blocks are organized.

Reproduce the reported import of adafruit_displayio_ssd1306 on CircuitPython 9.0 and inspect the try/import/except organization responsible for the compatibility imports. Done means importing the driver produces no warnings on 9.0 while continuing to work on 8.x.
