Describe changes:

The game is quite popular, with several tens of millions of players playing it every day, so I guess that support for detection of its traffic would not be superfluous.

The main issues are:

• Virtually all the flows contain some random-looking data, suggesting the traffic is likely encrypted.
• However, I've noticed that at the start of each new match, a new UDP session is started, and the 4th packet within this session consistently begins with 0xCE and contains the string LOC_PREFAB_LOADOUTNAME_1 in the first 100 bytes of the payload.
• I also noticed some short UDP sessions with a destination port of 7500, consisting of 2 packets with a payload length of 12 bytes, containing some random data and the string ping.
