Feat/cereal

[SuperFola]

New PR for #16 so that it lives on the repo (easier for me to do rebases to update the git history of the PR).

This adds loading and saving methods for:

• Entity -> this seems to fail when saving

• Engine

• Map

• Level

• Room

• Tile

• TCODColor

• Container

• Attacker

• Destructible

• Use

• As well as load_and_construct methods where appropriate

• Polymorphic Type Registration for MonsterDestructible WIP

• Added cereal as a dependency in vcpkg.json

Closes #13
