Adds the demuxer of animated WebP files.
It supports non-animated, animated, truncated, and concatenated files.
Reading from a pipe (and other non-seekable inputs) is also supported.
The WebP demuxer splits the input stream into packets containing one frame.
It also sets the timing information and

Adds support for decoding of animated WebP.
The WebP parser now splits the input stream into packets containing one frame.
The WebP decoder adds the animation related features according to the specs:

In the VT encoding insertion by FFmpeg,

The implementation of tag tree encoding was incorrect.

This patch fixes tag tree coding for JPEG2000 such tag
