Massive display overhaul

[harshil21]

Closes #54 when done.

To do:

• Add T- launch time
• Read all of the textual docs to understand how best to integrate and make the display
• Barebones: Get display working with mock imu
• Start adding graphs
• Add launch file selector with some options, with picture of the rocket along with relevant metadata
• Add downrange distance calculation in the (x,y) plane in meters, it should show live trajectory, and estimated trajectory.
• Add 3D model showing orientation of the rocket (not possible with textual, probably not worth using another library? Maybe a 2D model would have to suffice...)
• Detect drogue and main chute deployment
• Add debug panel for information (apparently only possible with a 2nd terminal)
• Integrate simulation speed into MockIMU
• Make everything pretty
• Tests with textual

Estimated lines of code to add: 1000+ python, probably at least a couple hundred for the CSS.
