Allow bytes as well

[caternuson]

For #24. Using bytes was essentially already supported. Just needed to let the driver know how cool it was.

Adafruit CircuitPython 6.1.0 on 2021-01-21; Adafruit QT Py M0 with samd21e18
>>> import board
>>> import adafruit_fram
>>> fram = adafruit_fram.FRAM_I2C(board.I2C())
>>> message = b'Python is fun!'
>>> fram[0] = message
>>> fram[0:len(message)-1]
bytearray(b'Python is fun!')
>>>

This is a bit weird for python because fram[0] = [0,1,2,3] would store the list at index 0, not treat it as a starting index. Instead you would use slices fram[0:3] = [0,1,2,3]. I believe this is how nvm works already. Mind look into switching this?

I was sort of wondering about that too. Do you think that'd be better as a separate issue?

I guess the idea was to make it easier? There's no way to actually store all of [0,1,2,3] at fram[0]. And that syntax doesn't require one to figure out the math for the slice values on the left hand side fram[0:3]. But I'm just guessing.

Fine with me if you want to do it later. I do think it'd be good to make consistent at some point.

Yep, agree. Just not sure how much of a thread it will pull to change here. And can use nvm as a reference. I'll open the new issue.
