Bricked Foundry

Adds molten stone, casting stone brick and casting rail recipe to the foundry.

Tries to be as close to vanilla balancing as possible:

• 199 molten iron, 21 stone for 42 rails in vanilla,
• 200 molten iron and (10 bricks/20 stone/400 molten stone) divided by 20 = 10 molten iron, 20 molten stone = 2 rails
• Crafting speed assembly machine 2 to foundry is usually 4 times the amount per second
• 3/s in assembly machine 2, 12/s in foundry

Complementary mods I use:

Foundry Expanded

Concrete Productivity Modified

Why?
Being able to smelt bricks in a smaller footprint on all planets. Especially useful on Fulgora.

And I just want to use foundries for everything.
