Decoding when pictures are skipped using SkipFrames (-s) does not work

Description

The VTM decoder includes a SkipFrames (-s) decoder option that skips a number of pictures before decoding. This feature seems to work in VTM-5.0 but does not work in VTM-8.0. In VTM-5.0, the decoder starts decoding at the next CRA picture after the skipped pictures.

I used these for testing:

bin/EncoderAppStatic -c cfg/encoder_randomaccess_vtm.cfg -c cfg/per-sequence/RaceHorses.cfg -q 37 -i /seqs/RaceHorses_416x240_30.yuv --IntraPeriod=32 -f 65 -b out.bit -dph 1
bin/DecoderAppStatic -b out.bit -s 1
