irregular expressions

(original comic: https://xkcd.com/208/)

I wrote a script to invert the luminosity of Wireshark packet colours, making it look better with dark themes.

- Export the existing colours with View > Coloring Rules > Export
- Run the script to modify the colours: ./wireshark-dark.py current-colours.txt > new-colours.txt
- Import the new colours
- Move them to the top of the list (or just clear all the rules before importing)
