One Spatial Dimension (#4570)

* Ported the "one spatial dimension" concept from pre-1.15

* Apply lighting updates after moving chunks.
Mark world data as dirty when changing it.

* Consolidated naming of spatial storage world/dimension.
Use server light manager to update lighting info in chunk.

* Save last transition information,
and add ae2 spatial command to interact with spatial storage.

* Formatting fixes.

* Improved docs for the origin generation.

Inverted condition on when the x/z axis are flipped.
Also added a helper to map a plot to a region file

* Remove TransitionResult since it's only used in lieu of a boolean.
Rework transition to make the checks BEFORE allocating a new cell.

* Removed unused imports.
