Introduced a new boolean property to prevent the use of the MPEG-TS container for live videos. This enables direct recording to an MP4 file without further conversions, which can significantly reduce hard drive IOPS.

By default, for live streams, yt-dlp writes to a MPEG-TS container and converts it to MP4 after the stream ends. Additionally, it adds hardcoded +movflags +faststart. As a result, this process uses approximately 3× the hard drive bandwidth: the TS-to-MP4 conversion requires reading the entire file and writing it again; the faststart flag further increases I/O, as it moves the moov atom from the end to the beginning of the file, requiring a full file read and rewrite.
Using --no-hls-use-mpegts for live streams forces yt-dlp to write the stream directly to an MP4 container. This can be useful in scenarios with limited disk IOPS or to reduce wear on SSDs with a low Total Write Bytes (TWB) limit.
