Platinum Fantina's Gym RNG

Secondary RNG (MT)

The routine first checks which door should be correct, then attempts to spawn the hint tile at a valid location

Which door should be correct: mtRand() % (# of doors, so 3 or 5 depending on room)
X Pos: mtRand() % length of room (15 or 27)
Z Pos: mtRand() % height of room (8 or 20)

The routine will keep attempting to spawn the tile until a valid location is found.

Valid locations in each room (Note that 1s are invalid tiles)
