Integration of Timed Metadata for HLS

[git-audo]

Hi, I worked on the support for HLS timed metadata as described in the Apple documentation [0]. Since the metadata is required to be in the ID3 format, I included a third party library [1] for the handling of this structure. If this could be of some interest it'd be great to know. I'd really appreciate a review of the added code, if someone has the time to do it. Thank you and good work!

Is this pullrequest working properly? When I tried, have an errror that it couldn't find id3v2lib, Is it solved by just adding the library?

Bump, will this ever be added into the main branch?

Never

I would say no, the last PR that was merged to master dates 5 years ago. Also when I wrote this code I still had a lot to learn, the quality of this implementation is not really that great. It would definitely need a rework.
