Kurt 67fc0d0885 Misc tweaks
Add Cap Pikachu const value updating for USUM, also set Magearna const for USUM (not only SM)
Remove `NotDistributed` property from WC3 as only CXD events used it, no longer WC3 type.
Delete ArrayUtil; move remaining methods into the StorageUtil class that used them for compressing/inserting bulk into boxes.
Add shiny wormhole flag
Extract byte array strings into spans, faster tests and less overhead.
