Seperate Audio Files for Engine Sounds, Thruster/Directional Thruster (Vectoring), and Idle

[Panzerv1Dev]

I've been noticing recently in the modding space that Avorion only has a single instance of the engine sound file for thrusters, engines (going forward), and idle. Having a seperate audio file instance for each action would allow some fun sound opportunities. A seperate file for engines when moving forward along side a different sound for vectoring would be amazing to have to improve the audio experience.
