@fweig

@se.gorbunov, @s.zharko: This MR splits the STS Hits into streams. Each stream is a separate partition but they aren't labeled separately. So you get multiple partitions with the same address. Each stream is now sorted in time.

Are there other changes required for the tracking? At first glance is looks like the tracking interface should be able to process this new format.

Unfortunately online tracking still has broken parameters, so I couldn't test it. :(
