 * Helper function to check if all of the pressure plates in the room are pushed.
 *
 * In this context, "pressure plates" refers to the grid entities that you have to press down in
 * order for the room to be cleared. This function ignores other types of pressure plates, such as
 * the ones that you press to get a reward, the ones that you press to start a Greed Mode wave, and
 * so on.
 *
 * Returns true if there are no pressure plates in the room.
