Functionality used before didn't widen the values from limited to
full range. Additionally, now the decoder uses BT.709 where it
should be used according to the video resolution.
Default for not yet set colorimetry is BT.709 due to most observed
HDMV content being HD.
BT.709 coefficients were gathered from the first two parts of BT.709
to BT.2020 conversion guide in ARIB STD-B62 (Pt. 1, Chapter 6.2.2).
They were additionally confirmed by manually calculating values.

Sometimes video fails to decode if H.264 configuration changes mid stream.
The reason is that configuration parser assumes that nal_ref_idc is equal to 11b
while actually some codecs but 01b there. The H.264 spec is somewhat
vague about this but it looks like it allows any non-zero nal_ref_idc for sps/pps.

src and dst are only 8-bit-aligned, so accessing them as uint16_t causes
SIGBUS crashes on architectures like sparc.
This fixes ubsan runtime error: load of misaligned address for type
'const uint16_t', which requires 2 byte alignment
