About

Added an Octo X rotor configuration for PX4 devices. The rotor poses were calculated according to NED's left hand rule.

How Has This Been Tested?

I changed the model in settings.json to "Octocopter" and adjusted the SITL none_iris PX4 target to use an octo_x mixer file. I tested with both a controller and a python script and ensured that not only did it fly smoothly, but that there were 8 actuator outputs.

Screenshots (if appropriate):

Hi @aaqibism! Were you testing this PR with a specific mesh for your octocopter? If so, is this mesh publicly available somewhere?

I tested with the default quad mesh.

Thanks for the contribution @aaqibism! Tested with commander and python script; looks to be working for me so I am moving ahead with merge.
