Audio API 0.13.2

WSOLA time-stretching on Android now runs through SIMD-optimized code paths, which cuts processing time in builds where the algorithm had been audibly falling behind (especially noticeable in dev builds). On iOS, an infinite recursion bug when the audio session has been invalidated is fixed.

What's changed

• Apply SIMD to WSOLA for faster Android time-stretching (#1163, @mdydek)
• Fix infinite recursion in the iOS audio engine when the audio session has been invalidated (#1167, @mdydek)
