A subclass of @c Track that provides its @c Events by querying a pulse-code modulated record of original

flux detections, with an implied index hole at the very start of the data.

The data may consist of a single @c PCMSegment or of multiple, allowing a PCM-format track to contain

multiple distinct segments of data, each with a separate clock rate.
