parcat does not consider slice_segment_address, which is not coded in the usual one slice only config. I also incorrectly counts each slice as a picture. 

I wrote a fix for parcat, see https://vcgit.hhi.fraunhofer.de/jvet/VVCSoftware_VTM/merge_requests/560

The fix however does not work if the macros HEVC_DEPENDENT_SLICES or ENABLE_TRACING are set.
