killing spree range check

proof of concept, probably not the best for in game usage

when killing spree is off cd, it shows a list of all targets in range, and puts an icon on their nameplates

doesn't actually work perfectly because:
1. IsSpellInRange only accepts string inputs for spells, and the string input for "Killing Spree" checks one of the various script spells that have a range of 0, so you cannot specifically check the range for killing spree

2. All range checks in this game work with absolute values, but when moving you have spell leeway which increases range, so all range checks will not work while moving

this aura just checks range 12 and it seems to work in practice?

this aura is also fucking cursed, it just hard checks nameplate1 -> nameplate15, cause making a custom code trigger to check every nameplate was too hard, and could be done without code. that might be an issue later idk how nameplate numbering actually works
