• Build the changes into the node library with npm run build
• Rebuild the data files: npm run data-files (This uses node so don't forget the previous step to build!)
• Close Brave
• Copy the local file you built to your profile extension directory: 
cp ~/Library/Application\ Support/BraveSoftware/Brave-Browser/cffkpbalmllkdoenhmdmpbkajipdjfam/1.0.135/4/ABPFilterParserData.dat
