Double-buffer storage wrapper for multi-pass stream transformations that require more than one storage array for streaming intermediate results back and forth.
Many multi-pass computations require a pair of "ping-pong" storage buffers (e.g., one for reading from and the other for writing to, and then vice-versa for the subsequent pass). This structure wraps a set of device buffers and a "selector" member to track which is "current".
