• Corrected issue where the wrong language is chosen in some cases.
  (Radarr and Sonarr don't use the same numeric language IDs, which is what the script was matching on. The script has now been updated to use the name of the language, not the numeric code.)
• Script will now try to set the language(s) in Radarr or Sonarr to what was retained after the video remux.
  This fixes the nagging 'Multi-Language' issue in Radarr, among other things. See issue #42 for more details.
  (The code is a little messy at this stage and may be tightened up later.)
• Added additional languages to codemap: Thai, Romanian
• Added handler for unknown language codes
• Added check for mkvmerge -J return
• Added multiple debug logging levels, defaults to lowest
  Default debug level excludes the returned JSON, making it more readable and useful
• Tightened up some jq code
• Updated help text and documentation
