updating octave's monster rules! the previous version just copy/pasted the bit from knave about converting monsters from D&D bestiaries but i feel like that doesn't work as well with octave, so it no longer relies on that.
added a bunch of example statblocks to better communicate what they look like in practice, so it's easier for GMs to homebrew their own.
i like how they turned out. nice and zelda-y
