fix parcat after recent HLS integrations
parcat has own functions to parse NAL unit header and slice header until POC. Those need updating after related HLS implementations (JVET-O0181, JVET-O0179)
Changes:
- slice header syntax
- NAL unit header in parcat
- NAL unit type numbers being redefined
Initial testing shows that this works now
