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:

And also with latest proposal for color format in mkv:
