Rewriting MCP230808 I2C Circuitpython library to use SPI for MCP23S08 chip

[ngmacha]

Following-up with adafruit/Adafruit_CircuitPython_Bundle#110, please help to modify the MCP23008/17 Circuitpython library to use SPI for the MCP23S08/17 chip.

This should go in the community bundle since its not carried by Adafruit.

Thank you - but could you kindly clarify: is that something that I'll have to take actions? Is this a wrong place to raise this issue?..

@ngmacha hiya, the issue can stay here. we don't have a plan to write this driver ourselves. if you plan to, or someone else can write it - we can include it in the bundle!

Hi folks! I was working my way through the Welcome to CircuitPython tutorial and was told to go to GitHub and look for an issue with the "good first issue" tag. I saw this one, and as it happens I'd added a couple of mcp23s08s to a parts order a while back as a "might be useful some day, since I'm paying for shipping anyway" thing.

So it's working now, blinkies blinking even as I type. I need to work through another tutorial to learn how to post/submit/request/etc my contribution and I still want to test it on a couple of other boards, but I'll plant my flag here since it's completed.

@timvgso Awesome! Thanks for your help! please let us know if you have any questions about the PR process.

Thanks @siddacious! The tutorial is very good so far for the Git side of it, and for coping with Travis as well. I'm feeling more overwhelmed by docs and examples for the new code to be honest, Sphinx, Readthedocs, .rst, .yml, etc. I'm sure the process is itself all documented somewhere but it feels like a big lift for a first-timer. One step at a time I suppose...
