this is the first half of an item check, where we're trying to figure
out whether samus get from her initial location to the item. (the second
half, where we want to figure out if she can get back, is below)
i'm not sure why these two items are singled out to get a full search
(no LimitArea). well - Item S0-05-16 makes sense since that's the
quarantine area item and you have to go through sector 6 to get to it -
but why the main deck data room?
bosses were considered unreachable when LimitArea was in effect because
they don't have a sector identifier (e.g. "S2") in their names.
this also affected non-boss things like the "Pump Control". now the
randomizer can actually require you to lower the water!
this heart of the randomizer, and it is the most complex function of the
bunch. it seems to function ok now, and the logic mostly makes sense,
but i wouldn't be surprised if there were one or two lingering errors.
