Every monster is assigned two bytes for the bestiary; one bit to count if their entry has been viewed
before, and the rest to counting the number of kills, up to 999.

I aim to reduce that to one byte per monster, limiting the number of recorded slayings to 99.
(If needed at some point, could further reduce to two bits; one for viewed, one for =>1 slayings)

This will free up plenty of space to store spell charge data for all PCs.

	-Start at VarMem+$C77...or rather $C78 for alignment

-Will not need to mess with the cross-game bestiary; it uses the same code as FF1 proper
	-Indeed, ought not to mess with it
