Update Tdarr_Plugin_henk_Add_Specific_Audio_Codec.js (#144)

* Update Tdarr_Plugin_henk_Add_Specific_Audio_Codec.js

Solves an issue where the plugin errors out on datatreams that do not have a copyright tag. It now only scans audio streams.
In addition, improved the routine, by checking if the desired output codex is already processed (not any audio stream)

* Fix lint issues
