[CORE] Map related decoding library

[PedroHLC]

• OG means "Original Game"
• RE means "Remade Engine"

OG map files uses it own binary format and old school things like look up tables and 16bit RGBA that though have it's own advantages are not well suited for modern graphics libraries, we will be using Nyxojaele documentation to learn how to decode this.

For starts, creating a library capable of decoding these resources out of the OG (keeping in mind its fidelity) will be my objective. Later we will have to discuss how this data will be organized used in the RE.
This is not a ripping utility yet, it justs splits data in something we developers can understand.

Also with this I'll be rewriting Nyxojaele documentation in a most complete way, it'll soon be available on Wiki.
