* Move to new options system. switch to using self.random reformat rules file. * further reformats * fix tests to use new options system. * fix slot data to not use self.multiworld * I hate python * new starting_items docstring to prepare for 1.20.5+ item components. fix invalid json being output to starting_items * more typing fixes. * stupid quotes around type declarations * removed unused variable in ItemPool.py change null check in Structures.py * update rules "self" variable to a "world: MinecraftWorld" variable * get key, and not value for required bosses.
