There should be a way to switch the QA401 into 192 kHz sample rate mode.

Do the first Reset() call when we are about to start streaming.

This seems somewhat cleaner, as this way we don't alter the state of
the QA401 until we actually start using it. Besides, this will help
with managing the state of register 5, especially since the sample
rate can only be changed when the QA401 is reset, but we don't know
the sample rate yet at ASIO init time.

See #2.

Optimize away log message formatting if logging is disabled.

This is required when running at 192 kHz sample rate due to the
extreme USB I/O timing constraints (there is only 5 milliseconds of
budget between the end of USB I/O and the start of the next one).

See #2.

At 192 kHz, make the default preferred buffer size 4096 samples.
94d90c9 
The previous default, 1024 samples, implies an unrealistic 5 ms
buffer processing deadline.

See #2.

Add an entry to the glitch FAQ about running at 192 kHz.
