Incompatible with PyBadge LC

[FoamyGuy]

I think this library currently assumes that if the I2C bus exists then the accelerometer will as well with the code from here:

Adafruit_CircuitPython_PyBadger/adafruit_pybadger/pybadge.py

Lines 60 to 73 in 75785b6

	if i2c is None:
	try:
	i2c = board.I2C()
	except RuntimeError:
	self._accelerometer = None
	if i2c is not None:
	int1 = digitalio.DigitalInOut(board.ACCELEROMETER_INTERRUPT)
	try:
	self._accelerometer = adafruit_lis3dh.LIS3DH_I2C(
	i2c, address=0x19, int1=int1
	)
	except ValueError:
	self._accelerometer = adafruit_lis3dh.LIS3DH_I2C(i2c, int1=int1)

Since the PyBadge LC does not have the accelerometer populated this ends up raising an exception.

We could possible handle the missing accelerometer more gracefully and allow the remaining portions of the library that are supported by the LC hardware to work.
