[Request] Add flow plugins to mark audio or subtitle streams as default

[Marnalas]

Hello, I had some need that I took the time to implement.

Basically I wanted to have two flow plugins:

• One for audio streams : that would mark a stream as default based on language (either manual or original language read from Radarr/Sonarr) and channels (either manual or highest count available) and whether descriptive streams are allowed or not.
• One for subtitles streams : that would mark a stream as default based on language (either manual or original language read from Radarr/Sonarr) and whether descriptive or forced streams are allowed or not.

I previously developped the applyRadarrSonarrNamingPolicy flow plugin and wrote the 2.0.0 version of the notifyRadarrOrSonarr flow plugin. All four of these plugins imply to be able to access the id used by Sonarr and Radarr, which I already implemented in these last two plugins.
While I was working on the two new plugins I started to think that it would be great (more efficient, maintenable, etc.) to share these duplicated features between the plugins. I remembered that a setFlowVariable flow plugin had been added. So I started working on an additional setFlowVariablesFromRadarrOrSonarr flow plugin that would read informations (ex: id and original language) and then store it in variables for use in the following steps of a flow.

Long story short, there are the pull requests for all of this work :

• setFlowVariablesFromRadarrOrSonarr v1.0.0 : Flow plugin set radarr sonarr flow variables #742
• ffmpegCommandSetDefaultAudioStream v1.0.0 : Flow plugin set default audio stream #743
• ffmpegCommandSetDefaultSubtitleStream v1.0.0 : Flow plugin set subtitle default stream #744
• applyRadarrOrSonarrNamingPolicy v2.0.0 : Flow plugin apply radarr or sonarr naming policy v2.0.0 #745
• notifyRadarrOrSonarr v3.0.0 : Flow plugin notify radarr or sonarr v3.0.0 #746

Here is an example of how to use all these plugins. It's my test flow, so it's normal that it doesn't really make sense in terms of logic.

there is one,
i assume this is what you looking for since there is no further info in your post

Yeah, I was still writing the message but I hit 'enter' by mistake. I completed the first message.
I will create the pull requests right away.

Pretty sure what I implemented doesn't already exist as reordering streams doesn't make a stream default.
