Consider adding m3u8 streaming parser to utils and install requirements

[stucka]

Additional details

At least one CivicPlus site has video links that go to an iframe with an embed that's calling upon a m3u8 playlist to retrieve the video pieces.

I think in an ideal world there'd need to be some code to figure out the URL to the playlist; figure out what the correct filename with extension would be; and code to get all this into a Metadata object. We'd also need code to be able to parse out a a URL for the playlist file, and the backend scraper would need to be able to actually parse the m3u8 playlist to get the multimedia files.

I have no experience with this, but a quick search turned up https://github.com/globocom/m3u8?tab=readme-ov-file ... There may be better choices out there.
