* Despite Opus Custom have strict requirements, it's more barebones, allowing us to use maximum frame size and custom sample rate, without resampling * Encode each frame size to network buffer, allowing smooth voice chat even in 10 FPS * Fix possible buffer overruns, underruns and races with platform side * Revise all usages of offset variables, samples vs bytes
