Details: * Switched SDL audio mutex to RW lock. This fixes games that continiously call SetVolume in a different thread (like Ghostbusters) * Added contition to buffer audio packets independent of video packets. This fixes choppy audio across many games. * Increased the number of audio frame buffers from 2 to 4. Just in case. * Migrated to std::jthread and std::mutex from pthreads. * Fixed a race condition with joins on avplayer close that caused a crash.
