[Enhancement] Support Invidious API

[ggtylerr]

Description
When sending a request to Invidious for a proxied video, you get a URL like this for its adaptive formats:

$ curl -s 'https://nyc1.iv.ggtyler.dev/api/v1/videos/2yJgwwDcgV8?local=true' | jq ".adaptiveFormats[0].url"
"https://nyc1.iv.ggtyler.dev/videoplayback?expire=1734441797..."

However, this URL will likely not work, as it's using Invidious' domain, not companion's. This means apps like FreeTube, PlasmaTube, Clipious, etc. won't work.

EDIT: It also looks like /api/v1/stats report that 0 requests are successful, which can mess with some uptime checkers.

Reproduction

1. Make a GET request for any video (https://domain/api/v1/videos/:id?local=true)
2. Try and use the URL given (under adaptiveFormats[i].url or formatStreams[i].url

Renaming this to supporting Invidious API, something that it is not a priority as of now.
