[extractor/voot] Fix extractor

[bashonly]

Voot's API almost completely changed; the only thing that didn't need to be rewritten is the series extractor.

Notes about the new version of the site:

• Geo bypass no longer works
• It is not possible to watch videos in browser or to access the playback API endpoint without authentication
• The auth token is not stored in cookies, so users have to pass credentials to yt-dlp with -u/-p or --netrc. Passing cookies will not work with the extractor. Can also authenticate with -u token, similar to the zee5 and sonyliv extractors
• Any resolution above 480p is now only available as DRM-protected DASH, at least for free accounts (have not tested with a premium account)
• The old video IDs are no longer available from the API

Closes #6715

Known Resolved issues:

• master m3u8s have "720p" and "1080p" resolutions, but when downloaded, the formats are actually only 480p. Need to see if these HD resolution HLS formats are available for premium users, or if the extractor should just remove them from formats altogether
  • RESOLUTION: if the m3u8 URL path contains /_definst_/smil:vod/, any format with a resolution above 480p will just be a duplicate 480p format (and higher resolutions are only available with the DRM DASH). However, the m3u8 URLs with /bpkvod/ in their path have true 1080p non-DRM formats available.

Summary

🆕📝🧪

Rewrite the VootIE extractor to improve compatibility and functionality. Use a new base class VootBaseIE that handles common logic and authentication. Support the new URL format that includes the show name and season. Extract more metadata fields such as series, season, episode, and duration. Update and expand the tests to cover the new features.

[bashonly]

Investigated the 720p+ formats issue further and pushed a fix.

RESOLUTION: if the m3u8 URL path contains /_definst_/smil:vod/, any format with a resolution above 480p will just be a duplicate 480p format (and higher resolutions are only available with the DRM DASH). However, the m3u8 URLs with /bpkvod/ in their path have true 1080p non-DRM formats available.
