Methods
filterForAVVariants_(manifest)
Take a series of variants and ensure that they only contain one type of
variant. The different options are:
1. Audio-Video
2. Audio-Only
3. Video-Only
A manifest can only contain a single type because once we initialize media
source to expect specific streams, it must always have content for those
streams. If we were to start with audio+video and switch to an audio-only
variant, media source would block waiting for video content.
