+As we ran onto an issue of having different volume levels for mono streams

+Each stream now has two sources - one panned to the left and one to the right,
+and uses two separate buffers to store data for each individual channel.
+For that we also have to reshuffle all decoded PCM stereo data from LRLRLRLR to
+LLLLRRRR (handled by CSortStereoBuffer).
