This begins the documentation of overlay009, which is in charge of
managing stuff related to the Distortion World.
For now, the scope of this commit has been limited to the following:
- start documenting structures used throughout this overlay, more
specifically the `DistortionWorldSystem` struct
- start documenting the structures found inside the files of the
`tw_arc.narc` NARC
- document functions and structures related to camera management inside
the Distortion Word, including the templates found inside the
`tw_arc.narc` NARC
