pixfmt: Add ARIB STD-B76 color transfer characteristic
Adding hybrid log-gamma (https://en.wikipedia.org/wiki/Hybrid_Log-Gamma) based on the standardization in ARIB STD-B67: http://www.arib.or.jp/english/html/overview/doc/2-STD-B67v1_0.pdf The choice of enum value of 18 is consistent with HEVC: http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=10481 And also with latest proposal for color format in mkv: https://mailarchive.ietf.org/arch/search/?email_list=cellar&gbt=1&q=Colour+Format+proposal Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
