Here index out of range was occurring so fixed to initialize the slice.

Thank you for the great repository!
I'm considering using pic_struct_present_flag for SEI analysis.
The comment in the code states that if BitstreamRestrictionFlag == 1, parsing may fail due to missing bits. However, it is unclear in which specific samples this issue occurs.
At least according to ITU-T H.264 (04/2017), the standard specifically defines both pic_struct_present_flag and bitstream_restriction_flag as 1-bit fields. I think it would be very useful to parse these fields.
