Reentry Burns

I've made reentry burns look way better. Reentry burns now take in all the details of your reentry, generate meshes and apply shaders to create a beautiful fiery streaky reentry burn across the bow shock and along the objects facing surface.

This was a good challenge. I looked to mods from KSP2 for visual inspiration on what I wanted to see and worked to take speed, direction, facing edges, and atmosphereic density into account to create a long streaky tail and a bow shock I could apply across every object, weapon, and vehicle in the game.
