Tommi 5d3e6805f2 Add audio view classes
From the new header file:
* MonoView<>: A single channel contiguous buffer of samples.
* InterleavedView<>: Channel samples are interleaved (side-by-side) in
  the buffer. A single channel InterleavedView<> is the same thing as a
  MonoView<>
* DeinterleavedView<>: Each channel's samples are contiguous within the
  buffer. Channels can be enumerated and accessing the
  individual channel data is done via MonoView<>.

There are also a few utility functions that offer a unified way to check
the properties regardless of what view type is in use.
