Program UART servos to work with PixHawk

[Giandroid]

Verify that the digital servos can work with the usually-analog PixHawk flight controller

After some discussion with @PrestonCazier on Discord, we've found that the LewanSoul LX-16A digital servos we'll be using will require a specific command sequence.

To interface them with the Pixhawk, we've found that we should be able to specify certain servo ports to use a custom script. The script can be written in Python 2, so we'll want to develop a library to work with the commands for the servos.

To make sure we can continue using these servos without buying a dedicated controller, we should test sending packets through an Arduino board. Please be sure to follow the baud rate and other specifics noted in the command protocol pdf

Awesome, can you make an issue to track developing the library?
