HEVC Parser (#9)

* basic parser create * adding data_stream * buildable parser * query output and required fucntions * latest changes * alloc buffer and other functions * parses first frame * parser finds all frames * parser dump size correct - dump file included * clean up * merge conflicts and file restructure * uses updated video demuxer * undoing changes to sample app * cleaning code * cleaning code * removing dwarf flag from compile * formatting changes * change variable names as per google standard * struct naming convention * struct name * remove parser data class and combine into parser buffer * remove context class and clean up * remove log file and use commons * move class to .h file * removing unused functions * removes platform.h * removing datastream class * formatting * remove byte_array, rename enums * clean up * spacing * rearrange to fit master * removes bit_strea_parser class, combines common stuff to roc_video_parser file
