Sound and cam

[kamatmihir2002]

1. Add improved sound logic
2. Add improved sound mixing and range compression
3. Better chase camera -- now tilts smoothly with car instead of using raycast-based tilt
4. Replay format is changed, although older files can still be played. It is not ideal however -- the sound is not correct and I'm working on improving sound support for older format replays. Other than that they work correctly. For the actual replay changes, I've added wheel contacts and whether a car is shifting gears in the current frame. (Let me know if i should undo this change specifically)

TODO:

1. Working on adding angle-based occlusion to SSAO calculation.

Suggesting changes in the future:

1. Adjustable SSAO samples based on quality preset, instead of a fixed 64.
2. Tonemapping. I know HDR is not in the game yet, but even with only SDR Tonemapping I think the aesthetic of the game could be controlled and improved.

Will need to change the destination branch to preferably something other than main. I chose main here because I started work with the main branch.
