dav1d 0.2.2 'Antelope', the fast and small AV1 decoder

This is the fourth release of dav1d, the fast and small AV1 decoder,
codename 'Antelope'.
It supports all the AV1 features and all bitdepths.

0.2.2 brings large improvements in speed on ARM64 and SSE3 (more than
10% speed increase) and even manages to gain around 5% on the already
fast AVX-2 implementation.

dav1d 0.2.1 'Antelope', the fast and small AV1 decoder

This is the second release of dav1d, the fast and small AV1 decoder,
codename 'Antelope'.

It still supports all AV1 features and all bitdepths, from 8 to 12bits,
and decodes more samples than before.

While still being the fastest decoder on AVX-2 CPUs, dav1d is now also
faster on ARM, ARM64 and SSSE3 CPUs in normal loads.
0.2.x is around 2x/2.5x faster on SSSE3 and achieves 1080p at 80fps
on an iPhone XS

0.2.1 is a small bugfix release above 0.2.0 to fix build issues, and
increase a bit the speed of SSSE3

dav1d 0.1.0 'Gazelle', the fast and small AV1 decoder

This is the first release of dav1d, the fast and small AV1 decoder,
codename 'Gazelle'.

It supports all AV1 features and all bitdepths, from 8 to 12bits.
It is very fast compared to other AV1 decoders on AVX-2 processors.

It has already SSSE3 and NEON code for other processors, and will get a
lot more of those optimizations in the future.
