Change acceptable number of output events in logParser

According to the discussion we had with @fsiegert @cgutscho I change the acceptable number of events (written in the EVNT file to): 1, 2, 5, 10, 20, 50, 100, 200, 500, 1000, 2000, 5000, 10000.

Also the timing checks are changed to that if we use 10k events (written in the EVNT) and the job is very fast, there is no error thrown.

This will be supplemented in a following MR with timing checks as discussed in #51 (closed) #45 (closed)
