map.contents always has 1200 tiles in it, there's no reason it should be
a vector.
This is a big commit because it requires changing all the level classes
to return a pointer to an array instead of returning a vector. Which
took a while for me to figure out, but eventually I did it. I tested to
make sure and there's no problems.
They are now stored in const int arrays instead. Except for the Prize
for the Reckless room, which I made sure had its spikes removed in No
Death Mode and the Time Trial.
