v0.0.4

Complete redesign / rewrite of the library! The version before this was basically just a prototype, but things are now on a good path architecture wise.

The document graph is now the central representation of the glTF, which in the future will be used for transform functions or extensions, or it can be interacted with for manual reading and writing to the glTF. IO formats can be created to convert to and from a graph. Current IO formats are for .gltf, .glb, and a Bevy -> graph exporter.

Additionally the library has been designed with glXF in mind, which is not yet supported but will be eventually.

There are still some major missing features, such as materials, which will be added soon™ in later releases.
