Improve/add several protocols (#1383)
Improve Microsoft, GMail, Likee, Whatsapp, DisneyPlus and Tiktok
detection.
Add Vimeo, Fuze, Alibaba and Firebase Crashlytics detection.
Try to differentiate between Messenger/Signal standard flows (i.e chat)
and their VOIP (video)calls (like we already do for Whatsapp and
Snapchat).
Add a partial list of some ADS/Tracking stuff.
Fix Cassandra, Radius and GTP false positives.
Fix DNS, Syslog and SIP false negatives.
Improve GTP (sub)classification: differentiate among GTP-U, GTP_C and
GTP_PRIME.
Fix 3 LGTM warnings.
