Update Audio Backend from Vs Camellia v2.75.1 (info at desc)

Browse Source 
Before anyone asks why vs cam, the code is public, plus i helped most of the audio backend rewrite in the mod too. :P

- Static sounds can now also seamlessly loop with AL_SOFT_loop_points extension
- Panning stereo sounds is now possible with AL_EXT_STEREO_ANGLES extension (although this was already implemented before)
- Improved streaming sounds, should fix most of the lagspike issues
- Streaming sounds should no longer regenrate if it's in the nearest timestamp (not for reversing though)
! You still can't access FlxSound.latency because of the new procedures that's not available in lime

If there's any crashes with this pls report an issue asap.
