Vimeo HLS/m3u8 download support

[blaaaaaaam]

I'm currently in the process of archiving a website using a locally installed Browsertrix Cloud instance. So far it's been working pretty smoothly and as expected.

However I've noticed an issue with Vimeo embed downloads/archiving.
Videos posted before at least September 2022 archive fine, but videos posted afterwards don't. The issue seems to be that links to .mp4 files which are usually in the 'progressive: []' array aren't generated anymore. There is this stack overflow issue that notes this and the change seems to have coincided with Vimeo's change to plans. My client is on a grandfathered plus plan which seems to not generate direct .mp4 progressive links anymore.

I have a test page here, which has two vimeo embeds. The first embed is the original upload from 2022, the second embed is the same video file but a new upload. The first embed archives fine, the second does not.

Is it possible for pywb to download videos using the hls .m3u8 links that are available?
