* adding ranged number type, for use in stats * Loaded Skills.txt * asset manager only binds terminal commands if terminal != nil * WIP stats * cache getter and clear methods were not implemented * asset manager handles a nil terminal pointer * adding skilldesc.txt loader (needs work) * ctc stat descriptions functions working * moving description functionality out of itemstatcost loader and into stats * stats seem like a central part of diablo, moving into d2core. * stats seem like a central part of diablo, moving into d2core. * delint * adding statlist, statlist reduction, unit tests * minor edits to stat.go * lint error in statlist.go * Remove dependency on actual data from mpq files stats unit tests now use mock data * fixing some lint errors, formatting Co-authored-by: Maxime Lavigne (malavv) <duguigne@gmail.com>
