eeprom.py SMBus needs to be closed

[sleepydog3]

You need to close the SMBus in read_eeprom. Best place would be in a finally part of the try. See https://pypi.org/project/smbus2/ example

I'm not so sure this really matters, but if it does we'd need to be a little more careful about where the .close() goes since we should not assume that the user wants to close an SMBus object they've passed into the function.
