Add basic reset support

[caternuson]

This is for #30.

This may or may not be a good idea. Hoping people in that issue thread can test this against their use case since they have actual fail cases.

I was only able to test happy path:

import time
import board
import digitalio
import adafruit_tca9548a
import adafruit_mma8451
import adafruit_bh1750

rst_pin = digitalio.DigitalInOut(board.D10)

i2c = board.I2C()
tca = adafruit_tca9548a.TCA9548A(i2c, reset=rst_pin)
mma8451 = adafruit_mma8451.MMA8451(tca[1])
bh1750 = adafruit_bh1750.BH1750(tca[4])

# initial readings
print(mma8451.acceleration)
print(bh1750.lux)

# reset
tca.reset()

# second readings
print(mma8451.acceleration)
print(bh1750.lux)

It works, but isn't super interesting since there was no actual failure that was needing to be recovered from.

I will await some user testing before approving.

@caternuson Code looks fine. So I won't merge, awaiting user testing, but merge when you feel confident.

I'm going to close this without merging since no one wanting this commented about it.
