PurrFX project update 6

Project status overview as of August 23, 2020.

Commits: From August 22 through 23 of 2020.

This time, I've updated different audio formats support (two bit depth modes and mono/stereo mode). Making the necessary changes directly to the “Game Music Emu” library is not an easy task. Therefore, I added a special proxy buffer to PurrFX that allows you to do audio conversion on the fly. This should not affect the quality in any significant way.

And the sound parameters are now defined by a special CAudioFormat class.
