--stat: Name of statistic to look for in ItemData.json. Must match the actual key, e.g. TechPower for Spirit Power
--statName: Column header in final table. TechPower isn't the name for the stat in-game, so change it here
--suffix: String to append to numeric value to indicate units. As of now only % and m/s are used in-game and in fact this is left blank for most stats
