Work on compatibility with porting lib on Fabric

* Change min/max section optimisations

* Correctly init dimension type

We need to initialise the field as early as possible in the constructor
to avoid problems.

Also, do not cache min/max section in EntityLookup. Note that mods
that implement worlds with variable heights will not work still,
as the entity slices expect a fixed height.

* Cache calculated height values
