David Harvey 0158397359 Legacy Session Frontend profiler should be less likely to lose the connection during live data preview. ...

Root cause was the Editor/UFE framerate dropping too low when there was a lot of stat data arriving. This meant the keep-alive Ping request from the game could not be acknowledged fast enough to avoid the 5s disconnection timeout.

 - decompress incoming stat messages via a task pipe to avoid saturating all cores.
 - only process a few stat messages per frame.
 - reduce the timeslice for stat aggregation during live data preview.

However, if bandwidth is saturated (typically by a very large amount of log spam being sent to the Session Frontend too) then the connection can still be lost.

Note: It's recommended to use Unreal Insights instead of the Session Profiler for UE5.
