fix: update package dependencies (#10)

Remove 'adafruit-board-toolkit' since we don't actually need it.

Replace 'adafruit-circuitpython-busdevice' with 'adafruit-blinka' since
we no longer need I2CDevice(). Unfortunately this doesn't really save
anything since blinka depends on busdevice. But it makes it a little
clearer what our own dependencies are and removes one layer of circular
dependencies.
