[v2.0.0] Implement dump function for all data types

[lmichaelis]

This is something which has been on my mind for a long time. phoenix should also support writing the files it parses so it can be used as a modern modding tool.

This requires merging the feature/flexible-buffers branch first and then implementing an archive_writer. After that is done, dump functions can be implemented for each file type.

Danger: especially for the VOb tree, it is critical that the correct object version numbers are saved!

The following has been done:

• [x] WriteArchive
• [x] VirtualObject and descendants
• [x] AxisAlignedBoundingBox
• [x] OrientedBoundingBox
• [x] CutsceneLibrary
• [ ] DaedalusScript
• [x] Date
• [x] Font
• [x] Material
• [ ] Mesh (partially done)
• [x] Model
• [ ] ModelAnimation
• [x] ModelHierarchy
• [x] ModelMesh
• [ ] ModelScript
• [ ] MorphMesh
• [x] MultiResolutionMesh
• [x] SaveGame
• [x] SoftSkinMesh
• [x] Texture
• [x] Vfs
• [x] World
• [x] WayNet
