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
