Catapult Tower
In the medieval times, catapults are not only used as siege weapons but also defensive weapons as part of their defensive fortifications.

The defensive emplacement is considered as a Tier-3 turret and thus, can only be crafted in the Workshop.
As for the catapult's model, it will use the Mangonel:

This allows the implementation to have an easier time lobbing projectiles than a sling-launched projectile from an Onager.
As for its projectile, it will lob blocks as a custom block entity under the Defensive Measures namespace, allowing for a broader customization. Said projectile will be under the Explosive Projectile base class and for now, will use Cobblestone. The reasoning behind the use of Explosive Projectile as base class is for a future implementation that will allow Block Projectiles to be explosive, depending on a configuration.
This turret will be part of the Tier-3 turrets, occupying a 3x3 area and can only be crafted with the 9x9 bench called Workshop.
