Subject: ndpiReader: improve the check on max number of pkts processed per
 flow (#2261)

Allow to disable this check.

I don't know how much sense these limits have in the application
(especially with those default values...) since we have always had a
hard limit on the library itself (`max_packets_to_process` set to 32).
The only value might be that they provide different limits for TCP and
UDP traffic.

Keep them for the time being...
