Add parsing of the lhvC Configuration parameters from MP4. These are used for MH-HEVC bitstreams. Unfortunately, FFmpeg does not support reading this yet and it also does not give us these in the extradata. So the solution for now is to just open the input file "raw" and search for the characters lhvC. The sequence is searched for in the first and last 5k of data in the file.
This is very hacky but there is no other way unless we would have our own mp4 parser.
