The end result of these rules is palette adjustments, so there's no
reason to create custom code for each effect. Searching for palette
mods has an O(n) complexity, but the dataset is quite small, so it
should be negligible.
This adds a devtools script to convert scifx config files from FreeSCI
into C++ code to apply the palette mods.
The actual palette mods are by Matt Hargett, and from FreeSCI.
