NALread.cpp convertPayloadToRBSP not called correctly

NALread.cpp function convertPayloadToRBSP is not called correctly from read().
The parameter "isVclNalUnit" is set true if bit 6 of nalUnitBuf[0] is 0.

In HEVC, this correlated with nal_unit_type, bit 5, which was 0 for all VCL NUTs (and 1 for all non-VCL).

In VVC, this currently corresponds with bit 4 of nuh_layer_id.
It probably should instead be based upon (nalUnitBuf[1]&31)<12.

The impact is to remove trailing 0s from non-VCL NAL units, prior to interpretation, which may not be desired.
