[FEATURE REQUEST] Audio and Video Metadata

Hi, 
I don't have the skill to implement this (yet).
I think it would be cool to be able to insert metadata from _jpeg, png, mp3, mp4, and wav fx._ into the name.
like **Author, Title, Genre, Time, ISO, Length** and stuff.
I saw a thing called ExifTool if that helps.

Something similar is implemented in `Czkawka`.

Thanks in advance if you decide to do it and thanks for the tool :)
