This class is designed for use in non-simplistic cases. For AudioUnits, AUBufferList
is preferred.
CABufferList can be used in one of two ways:
- as mutable pointers into non-owned memory
- as an immutable array of buffers (owns its own memory).
All buffers are assumed to have the same format (number of channels, word size), so that
we can assume their mDataByteSizes are all the same.
