DistByte is actually 16bits; no point changing the name.
The 32bits afterwards are form duration (Hoopa/Furfrou only), and only
exist while the PKM is in the player's party.
The game sets an initial value with days to exist in the form before
reverting (probably on game restart), checking the delta between days
saved. Either way, just set a base value when writing it to the party,
else clear the value if it is not supposed to be used.
Thanks @SciresM !
