- Add u4_enable_hbd member to ihevcd_cxa_create_ip_t and codec_t. - Return error in ihevcd_parse_sps if u4_enable_hbd is 0 and bit_depth_luma_minus8 or bit_depth_chroma_minus8 are non-zero. - Initialize u4_enable_hbd to 1 by default in main.c, DecHelper/DecTests, and hevc_dec_fuzzer.cpp. - Add --enable_hbd command line option in main.c. - Add test in DecTests.cpp to ensure decoder returns an error when decoding 10b clip with u4_enable_hbd set to 0.
