 * Interface to write Ion value to bytes over a variety of destinations.
 * Avoiding the Java standard overhead in so far as possible.
 * This requires the ability to access any part of the underlying
 * data source randomly and insert space at any position.  However forward
 * access is expected to be the standard direction.
