Explore how to use MAVSDK server for ArduPilot

I've recently asked in the ArduPilot community on Discord if it's possible to use `MAVSDK` for ArduPilot.
Apparently, the `MAVSDK` server is hardcoded for `PX4` specifically and there might be more than a few differences.

This should be explored so that we can see what it would take to use the `MAVSDK` server for ArduPilot.

> Basically mavsdk will runtime detect which autopilot it connects to, but some functionality is hardcoded to px4 - for instance Ardupilot uses waypoint 0 to store the home location, so missions are effectively indexed from 1. Px4 doesn’t, so missions are indexed from 0. Takeoff, land, etc should work.
