LibVideo: Allow the VP9 decoder to decode ultra high resolution video

Browse source 
Previously, some integer overflows and truncations were causing parsing
errors for 4K videos, with those fixed it can fully decode 8K video.

This adds a test to ensure that 4K video will continue to be decoded.

Note: There seems to be unexpectedly high memory usage while decoding
them, causing 8K video to require more than a gigabyte of RAM. (!!!)
