Create function to create the shorter binary of the world about ecs

[osvegn]

Informations should contains world information.
A world contains each of those part: resources, entities and systems.
A resource contains a type and a data.
A entities contains an ID and a list of components.
A component contains a type and a data.
A system contains a type and a state.

The way to perform a good world image in this ECS should be this way:

• 4 control bytes (such as magic number)
• (1 byte for now) 2 bits to know which element follow (resources description: 00, entities descriptions: 01, systems descriptions: 10)
• 00 [
  • 1 byte to know the number of resources (0-256)
  • [
    • (1 byte for now) X bits to fit resource different type count, which describe the type
    • 1 byte for the size of resource data in bytes
    • Y bytes of data
      ]
      ]
• 01 [
  • 16 bits to know the number of entities (0-65 535)
  • [
    • 16 bits to know entity ID
    • 8 bits to know the number of components
    • [
      • X bits to fit component different type count, which describe the type
      • 8 bits for the size of resource data in bytes
      • Y bytes of data
        ]
        ]
        ]
• 10 [
  • 8 bits to know the number of systems (0-256)
  • [
    • X bits to fit system different type count, which describe the type
    • 1 bit to know if it is active or not
