Add --metric-no-group that causes all events within metrics to not be grouped. This can allow the event to get more time when multiplexed, but may also lower accuracy. Add --metric-no-merge option. By default events in different metrics may be shared if the group of events for one metric is the same or larger than that of the second. Sharing may increase or lower accuracy and so is now configurable.
