Additional turrets

Additional Turrets are back.

continuing the work of DarkNova

I did some rebalancing, for a more vanilla approach. You can still change ATK and ATK-SPD in the mod options if you deem it neccessary.

If you think some of the ammo is under or overperforming pls let me know i will try my best to test and if neccessary adjust it.
