* move music path enumerations into d2resource * move text dictionary (.tbl) loader into d2fileformats sub-package d2tbl * lint fix, add doc file for d2tbl * moved data_dictionary.go into d2fileformats sub-package d2txt, added doc file * added sub-packages d2geom for geometry-related things, and d2path for path-related things * moved calcstring.go to d2calculation * move bitmuncher, bitstream, stream reader/writer from d2common into sub-package d2datautils * fix lint errors in d2datadict loaders (caused by moving stuf around in d2common) * move size.go into d2geom * move d2common/cache.go into sub-package d2common/d2cache * renamed d2debugutil to d2util, moved utility functions from d2common into d2util
