provide flag for controlling log verbosity

[mmguero]

💡 Summary

Some of the ICSNPP parsers can be very verbose (e.g., as far as individual values for writes/reads/operations vs. higher-level operations). It would be convenient to provide a flag to be able to control the verbosity of these logs per-protocol. In other words, a boolean where if set to "true" the verbosity is higher (i.e., more of the .log files are generated) vs. "false" where only summary logs are generated (not the details).

Motivation and context

This idea came from the discussion we had with corelight.

Implementation notes

An example of this could be the synchrophasor parser. See main.zeek.
