Describe your changes

Added Water Seven 19

Not sure if exceptions.json and the .nfo files should have been edited, given the overlap with the next (unreleased) episode. Left untouched for now.

Checklist for submitting new .nfo files

• [ ] I have removed the old .nfo files that are being replaced
• [x] I have validated that the new .nfo file works correctly in Plex
• [ ] I have updated the README, fixing the list of current missing episodes
• [ ] I have modified exceptions.json, removing any exceptions no longer required
