Compare LogEvent by full instant time

Replace nano-of-millisecond comparison with a combined Instant-based time. The comparator now imports org.apache.logging.log4j.core.time.Instant and uses a new getTime(LogEvent) that adds instant.getEpochMillisecond() and instant.getNanoOfMillisecond() (returning a long) for ordering, instead of comparing only getNanoOfMillisecond(). Method renamed and return type adjusted accordingly.
