Jetson servo board ros2 Node

[TheDinner22]

task description

We have this board for the Jetson. We want software that sends PWM over the Jetson's GPIO.

ROS structure

Ideally it's one node with a service, you can send the PWM frequency and optionally a timeout (no timeout means infinite).

optional stuff

maybe a stop all/kill service too so that mechanisms don't try and move the sub is killed.

please don't

use any other pins besides pwm :)
