Brewing Stands Converting Magma Cream into Slime Balls

Using magma cream as fuel in a brewing stand should provide half the fuel that blaze powder provides, and also convert the magma cream into a slime ball, since the blaze powder in it would be removed. This would add an interesting gameplay feature for players who want to attempt a nether-only playthrough, but still want access to slime. It would also lead to some interesting farm designs and encourage nether-only players to use brewing stands more in order to exhaust fuel to allow for the conversion of magma cream.
