M3u8MultiVariantInputNode class

see: NorskInput.m3u8MultiVariant()

Pulls an HLS master playlist and emits a single set of streams covering every TS rendition the master enumerates. All renditions share one TimeDomain, so their timestamps are anchored to a common clock.

Subtitle (EXT-X-MEDIA TYPE=SUBTITLES) renditions are not consumed by this input today - use NorskInput.m3u8WebVtt per subtitle rendition for now.
