Develop Python interface to sdgps `robosub-ping-solver`

[cbrxyz]

What needs to change?

Thanks to the great, amazing, fantastic work of Sylphase, we have a great tool for solving the localization problem with underwater microphones. We will need to develop an interface to this solver, so that we can obtain the locations of the pingers underwater at RobotX.

How would this task be tested?

1. Ensure that the library can communicate with the sdgps library.
2. Write some tests for the library.
3. Ensure that the library is able to communicate with the Sylphase board when ROS is launched/the boat is launched.
