steveanton 9465fe2f98 Add low level audio mixing algorithms
Adds the AudioMixerAlgorithm interface which allows for specialized
implementations of audio mixing that also efficiently convert between
source and mixing formats.

Initial implementation has two algorithms:
1. Float -> float (with channel mixing)
2. S16 -> float (with channel mixing)
