Add a feature to the run.py that will "advertise" the robot IP address using the neopixel lights

The driverstation has to know "where" the robot is (the ip address), so it can connect to it.

On a home network, it will likely have an address like:

192.168.0.nnn

or some variation thereof. So, the robot could "advertise" that last quantity with some flashing lights.

You could pick 3 lights to advertise the digits on the "nnn", and they could do it with just flashing a number
of times for the digit.

So, for 163:

light1: flash, pause, pause, pause
light2: flash, flash, flash, flash, flash, flash, pause, pause, pause
light3: flash, flash, flash, pause, pause, pause

Once we have the run.py starting automatically, this will help the driver know the address to connect
to without using rendevous protocol (which windows likely won't have), or a statically defined address (which may not be possible to configure on some home networks)

Notes on the implementation:

The most straightforward way to do this would be to create 3 separate threads that each do a digit.
Write a general purpose function digit_flash(n) that will do the right thing, and then create each thread
with the proper argument and digit_flash() as the function.

We can maybe have a control on the driverstation to turn it off (once things are connected).

P.S. I would *love* to work on this project. Oh to be young again.
