Add support for season.nfo in collections for Emby

[Kamaroth92]

Media player: Emby

I have a suspicion this will also effect Jellyfin from reading some comments but it looks like at least Emby doesn't support the namedseason field in tvshow.nfo. I can confirm if I use a season.nfo file inside the collections season folder Emby picks it up as expected.

Is it possible to either add support to generate a season.nfo file inside of the created season folder (similar to the other nfo creation plugins) or to refactor the nfo_* plugins to allow for generic nfo file creation which might make it even more flexible?

just installed ytdl-sub with Emby and just noticed this today as well.

I was having a look at trying to resolve this using the existing nfo_tags plugin which I did get a working example but it also then causes the episode nfo_tags to not get created. I had a closer look at the codebase and see that you also have a generic nfo creation class that the output nfo plugin is using so I extended that to also support season.nfo in the season collection directory and added it into the Jellyfin preset.
