Expose I2C Bus

Feature request for future revisions of the board:

Have an unpopulated 4-pin header that exposes the i2c bus (plus power and ground) for external devices. Currently I'm just soldering a port to the resistors near the LED controller, but it'd be easy and free to just incorporate this into the board design.

For anyone curious on how to do this, here is a zoom in of the header I added near the LED driver (chip next to the QR code behind the spacebar)

From top to bottom is (GND, VCC, SCL, SDA).
