Create an ESP32 demo talking I2C to an accelerometer. #18

We want the ESP32 demo at firmware-esp32/ to be capable of reading data from an accel-mma84 module over I2C. The MVP would be reading acceleration data and turning on lights when e.g. the board is flipped over. We will later abstract this working accelerometer demo to build our firmware support for I2C.

I could do this, but I don't know if I have that accelerometer. Let me check my stash before I commit to anything.

If I can find the time this weekend I can take a stab at this - just found an old accelerometer module.

As an aside I also just put up some code I'm working on which has an esp32 successfully talking to the Tessel IR module over SPI -> here. My next steps for that one are getting a basic GATT server set up and sending IR commands through lightBlue on my laptop.
