Testing overhaul phase 1

Now have test black, white, primary, secondary, overblown, and negative

Actually everything looks good except JzAzBz of course, but that's what
encouraged me to make this test in the first place.

Idk how to fix it tbh, NaNs aren't fun.
I'll have to look at the matlab or python code see if they have guards.
