Add support for dynamic music

[Koddra]

I absolutely loved KSP2's music, it was like the only good thing that game created. The thing I loved about it was that it was dynamic meaning that when the conditions changed, the music also very smoothly changed. So during reentry the music would get more energetic. I know that I'm not the only one who liked this because there is already a mod for adding KSP2's soundtrack into KSA. Due to the current limitations however, the author of that mod was unable to add the dynamic effect into the game and just picked one soundtrack for each planet.
I absolutely understand that this is not something important and that you are mostly working on the physics engine and such. Adding this in the future might already be your plan, idk. All I'm saying is that I feel like this would be a great addition to the game.
