Rostislav Pehlivanov 1b8649c2ce opus: add an option to toggle intensity stereo phase inversion 
Due to a somewhat high volume of complains, phase inversion has
been made optional with RFC8251. This allows for better bass
frequency response when partially downmixing to play on systems
with an LFE speaker.
