Lavaplayer fails to play Vimeo tracks due to empty "progressive" array, causing NPE

[freyacodes]

Upon playing a Vimeo track, Lavaplayer downloads a track config from which it extracts request.files.progressive[0].url. However, on some tracks the progressive array is null, resulting in a NullPointerException. It appears that we need to add support for hls or dash.

Example url: https://vimeo.com/783006175

Track config url: https://player.vimeo.com/video/783006175/config?autopause=1&byline=0&collections=1&context=Vimeo%5CController%5CClipController.main&default_to_hd=1&h=250a7cefe0&outro=nothing&portrait=0&share=1&speed=1&title=0&watch_trailer=0&s=6ae0e5726574100d746264e851da4ccf6e8bd963_1704285204

Looks like there are multiple CDNs as well, this is something to keep in mind when retrying to load the stream if one of them fails

Although I do not plan on any elaborate CDN fallback, I have been able to get HLS working. I will be submitting a PR later.
