win-capture-audio v2.2.0-beta

For OBS versions 27.1.3 and newer, on (an updated) Windows 10 2004 (released 2020-05-27) or later.
This is (as with previous releases) a beta release - use at your own risk.

WARNING: This release has a major issue with the internal mixer logic, use v2.2.1-beta or later.

• Switches to tracking sessions using IAudioSessionEnumerator and friends, and removes old window selection logic - capture of processes without windows is now supported.
• Implements custom mixer to handle capture of multiple processes, required for the session tracking.
• Exclude session option re-written to capture all non-matching sessions rather than using the ProcessLoopbackParams flag - now works even when the target session does not exist.
• Remove MMCSS MF queues (potential source of instability?).
• Fixes for UWP windows with hotkeys, capture of elevated processes and a couple potential deadlocks (thanks @walker-WSH!).
• Fix OBS hanging on exit (probably...).
• Minor installer improvements.

You will most likely have to re-add your win-capture-audio sources if upgrading from a previous version.
