Modify the fireBullet method in the Hero class to shoot 5 bullets at a time
User prompt
make the spaceship shoot 3 bullets at a time
User prompt
increase the spaceshooter bullets from 1 to 3 and they should spread like at an angle apart the left to the left, the middle goes straight the right bullet to the right where the left and right spread at a slight angle as they go up into space
