ghidra doesn't like enums with negative values

[BenLubar]

starting an enum at -1 means ghidra adds 1 to every value, resulting in nothing matching up with what it should. in most cases, the only negative enum values are NONE = -1 or something equivalent, so we can just skip those.

I wonder if anything has changed... somewhere. I remember this problem but the scripts were working somehow before.

They work, it's just that enums that have a NONE value end up offset by 1
