Added multichannel WDM support (surround sound).

Improvements

• Added multichannel WDM support (surround sound)
• Added option to expose multiple WDM inputs and outputs (Analogue, S/PDIF and Loopback channels)
• Renamed “LOCKED” to “SYNCED” to avoid confusion around clock status.
• Numerous stability and performance improvements.

Bug fixes

• Fixed an issue that caused some DAWs (Studio One, Reason and Sibelius) to expose unsupported buffer size options.
• Fixed an issue that could cause glitching on systems with some older AMD processors (Phenom-II, FX and Athlon series).
• Fixed an issue that could cause glitching when using more than one ASIO application at the same time.
