Feature Request: Python 3 Support

[santaimpersonator]

Currently, the ROS nodes (?) utilizes Python 2 for the hardware scripts, which was announced to be sunset a while ago: https://www.python.org/doc/sunset-python-2/

If the nodes (?), were to utilize Python 3, I could add in the functionality for the OLED display included in the SparkFun Kit: #37 (comment)

I don't think the source for the Python nodes are specific to Python2, it's that ROS Melodic uses Python2. So ROS will run them with Python2 and not Python3.

Thanks, I wasn't sure where that happened. I'll take a stab at some of the instructions online for running ROS-Melodic with Python 3: https://www.miguelalonsojr.com/blog/robotics/ros/python3/2019/08/20/ros-melodic-python-3-build.html

If I find something that works, I'll submit a pull request with the added hardware code and updated setup/installation instructions.
