Automated anomaly detection
Compute per-track mean, variance, and n*stddev stats for the first u32
datum in each instance of the supplied event.
Search for the next instance of the indicated event which has a datum
larger than mean + n*stddev.
This turns out to be a very effective "Nixon Gap" finder when the
selected event datum is the instantaneous vector size. Such traces can
be easily captured from production vpp images.
