Make startup script to speed up testing

[iandareid]

Currently it takes 8 or more commands to launch ROSplane in a sim environment. It is even more for a flight test. This significantly slows down the ability to test. We need to have a script that can in no more than 2 commands get the entire environment set up.

The script will use tmux to create a session and then run the commands. There are issues that have long been neglected in the calibration process that need to be resolved to make the script reliably only 2 commands. However, as it stands it is a major improvement to even have the environment set up.

The script will need to be dynamic to either be used for sim or a real life flight test.

The script is written and works well for simulations. It needs to be refactored to be in rosflight_gcs. It also needs testing on real world remotes.
