Add header for external sensors #29

Unsure exactly what this would look like, but eventually we will need a way to add new novel sensors to the device. It could be something as simple as adding pins for the I2C lines. Open to ideas.

Through my experience with the bme280 sensors, we can add a 1mm JST connector (commonly known as Quiic Connect from Sparkfun or STEMMA QT from Adafuit. There's also a standard 2mm JST connect that's used by some Adafruit products as STEMMA and Seeedstudio as Grove. We can easily crimp a 1mm to 2mm JST or have it breakout into jumper wires. Thinking about adding multiple terminals to make it easier to add multiple devices.
