Create `sdgps.service` on NaviGator

[cbrxyz]

What needs to change?

Rather than needing to start our GPS each time we turn on NaviGator, it would be better to have a systemctl service to automatically launch the GPS when the computer is started.

How would this task be tested?

1. Ensure that the GPS is automatically launched when the boat turns on.

This week I created a file called start_gps.sh inside Navigator's scripts folder that creates sdgps.service, which runs NaviGator/mission_control/navigator_launch/launch/hardware/gps.launch. Start_gps.sh also runs commands which set up the service. I also configured the on_boot file inside the scripts folder to run start_gps.sh upon running, which should start the GPS when the Navigator computer starts. I still need to test the code to ensure everything runs smoothly.

This week, I began testing my GPS start code but I ran into a few errors getting the service to start when the Navigator simulation starts. Therefore, I will research more into systemctl files and how to run them automatically through Navigator's starting code.

I was not able to get much done this week due to exams but I continued researching systemctl files and trying to run them in Navigator's starting code.
