Refactors projectile prediction engine

Refactors the projectile prediction engine by introducing an interface
and making the legacy implementation more flexible.

The legacy engine is updated to allow for coordinate system customization
through virtual methods, enabling usage in different game environments.

Also introduces vcpkg support for easier dependency management and adds boost-asio as a dependency.
