Write Scan the Code mission

[kev-the-dev]

Write the scan the code mission, which will

• Get the location of the challenge from the object database
• Move in front of the object so the cameras can see the LED panels
• Wait or circle the platform until the perception reports the color sequence
• Set the parameters of what was seen

The mission we used in 2016 is here. This can be a starting point but will likely need to be changed to work with the perception in #242.

In the current mission, the perception is done from within the mission script. In the new version, the perception should be a separate program which the mission interacts with through topics/services.
