Add support for TVHeadend

[joaquinito2070]

I can't add M3U lists in my TVHeadend, because are not compatible. I need to add support for TVHeadend.

The playlist is already in a format that TVHeadend can read and process. TVHeadend supports standard M3U playlists, as long as they have the #EXTM3U header, followed by #EXTINF tags for each channel along with stream URLs.

If you’re running into issues adding it, could you let me know exactly what’s happening when you try?
